Description

Technical Field

[0001] This invention relates to the field of concrete-filled steel tubular columns, and more specifically, to a method and system for testing concrete-filled steel tubular columns. Background Technology

[0002] Concrete-tube steel columns are a common structural component. They mainly consist of steel tubes and tie bars and positioning bars installed inside the steel tubes. The tie bars and positioning bars are welded together. They are widely used in construction engineering and other fields. With the continuous development and progress of the construction industry, higher requirements have been put forward for the safety, reliability and durability of building structures. Concrete-tube steel columns are widely used in various construction projects due to their unique advantages, such as high load-bearing capacity and good seismic performance.

[0003] During construction, deviations may occur in the fabrication of steel pipes, causing the physical dimensions such as the thickness and diameter of the steel pipes to deviate from the design standards, thereby affecting the performance of the steel-concrete composite column. At the connection points between various structures of the steel-concrete composite column, if the number of welding points is reduced, the performance of the steel-concrete composite column will be affected, which may lead to hidden dangers at the structural connection points.

[0004] Existing methods for inspecting concrete-filled steel tubular (CFST) columns often focus on testing single indicators, such as the strength of the concrete or the thickness of the steel tubing. They lack comprehensive testing and analysis of the structural condition of the CFST column and the condition of the connections between structures. This makes it difficult to accurately and comprehensively determine whether the performance of the CFST column is normal, and to detect potential quality problems in a timely manner, thus posing a threat to the safety of the building structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a method and system for detecting concrete-filled steel tube columns.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for testing concrete-filled steel tubular columns, the method comprising the following steps:

[0008] The inspection includes the status information of each structure of the steel-concrete composite column during construction and the status information of the interconnections between the various structures of the steel-concrete composite column during construction.

[0009] The structural state set is obtained by comparing and analyzing the state information of each structure of the steel-concrete composite column during construction with the state information of each structure of the standard steel-concrete composite column; wherein, the structural state set includes normal physical state information, beneficial physical state information, harmful physical state information, normal structure quantity information, increased structure quantity information, and missing structure quantity information.

[0010] The condition information of the interconnections between various structures of the steel-concrete composite column during construction is compared and analyzed with the condition information of the interconnections between various structures of the standard steel-concrete composite column to obtain a set of structural connection conditions; wherein, the set of structural connection conditions includes normal condition information, beneficial condition information, and harmful condition information of structural connection.

[0011] The performance of concrete-filled steel tube columns is judged to be in a normal state by comprehensively considering beneficial physical condition information, harmful physical condition information, information on increased structural quantity information, information on missing structural quantity information, beneficial condition information at structural joints, and harmful condition information at structural joints.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This technical solution comprehensively acquires various data of the steel-concrete composite column during construction by detecting the status information of each structure and the condition information of the interconnections between structures. This provides rich and accurate data for subsequent performance assessment. By comparing and analyzing the various information during construction with standard information, a set of structural status and a set of structural connection conditions are obtained. Then, by comprehensively judging whether the performance of the steel-concrete composite column is in a normal state through the information in these sets, potential problems of the steel-concrete composite column can be accurately identified, which helps to discover potential quality hazards.

[0016] The embodiments further illustrate the detection method and system for steel-concrete composite columns proposed in this invention.

[0017] A method for testing concrete-filled steel tubular columns, the method comprising the following steps:

[0018] The inspection includes the status information of each structure of the steel-concrete composite column during construction and the status information of the interconnections between the various structures of the steel-concrete composite column during construction.

[0019] The structural state set is obtained by comparing and analyzing the state information of each structure of the steel-concrete composite column during construction with the state information of each structure of the standard steel-concrete composite column. The structural state set includes normal physical state information, beneficial physical state information, harmful physical state information, normal structural quantity information, increased structural quantity information, and missing structural quantity information.

[0020] The condition information of the interconnections between various structures of the steel-concrete composite column during construction is compared and analyzed with the condition information of the interconnections between various structures of the standard steel-concrete composite column to obtain a set of structural connection conditions; the set of structural connection conditions includes normal condition information, beneficial condition information, and harmful condition information of structural connections.

[0021] The performance of concrete-filled steel tube columns is judged to be in a normal state by comprehensively considering beneficial physical condition information, harmful physical condition information, information on increased structural quantity information, information on missing structural quantity information, beneficial condition information at structural joints, and harmful condition information at structural joints.

[0022] Since concrete-filled steel tube columns mainly consist of steel tubes and tie bars and positioning bars installed inside the steel tubes, and there are welded joints between the tie bars and positioning bars, the status information of each structure of the concrete-filled steel tube column during construction in this application mainly refers to information such as the thickness of the steel tube, the length of the steel tube, the thickness of the tie bars, the thickness of the positioning bars, the number of tie bars, and the number of positioning bars. The status information of the interconnection between the various structures of the concrete-filled steel tube column during construction mainly refers to information such as the status of the welded joints between the tie bars and positioning bars.

[0023] The state information of each structure of the standard steel-concrete composite column described in this application mainly refers to the state information of each structure of the steel-concrete composite column under standard conditions. This application compares and analyzes the state information of each structure of the steel-concrete composite column during construction with the state information of each structure of the standard steel-concrete composite column to obtain normal physical state information, beneficial physical state information, harmful physical state information, normal structure quantity information, increased structure quantity information, and missing structure quantity information.

[0024] For example, if the state information of each structure of a steel-concrete composite column during construction is compared and analyzed with the state information of each structure of a standard steel-concrete composite column, and the steel pipe thickness in the steel-concrete composite column during construction is equal to the steel pipe thickness in the standard steel-concrete composite column, then the steel pipe thickness is considered to be in normal physical state.

[0025] For example, if the state information of each structure of a steel-concrete composite column during construction is compared and analyzed with the state information of each structure of a standard steel-concrete composite column, and it is found that the thickness of the tie rod in the steel-concrete composite column during construction is greater than the thickness of the tie rod in the standard steel-concrete composite column, then the thickness of the tie rod is a useful physical state information.

[0026] For example, if the state information of each structure of a steel-concrete composite column during construction is compared and analyzed with the state information of each structure of a standard steel-concrete composite column, and it is found that the thickness of the positioning reinforcement in the steel-concrete composite column during construction is less than the thickness of the positioning reinforcement in the standard steel-concrete composite column, then the thickness of the positioning reinforcement is harmful physical state information.

[0027] For example, if the status information of each structure of a steel-concrete composite column during construction is compared and analyzed with the status information of each structure of a standard steel-concrete composite column, and the number of positioning bars in the steel-concrete composite column during construction is equal to the number of positioning bars in the standard steel-concrete composite column, then the number of positioning bars is the normal structural quantity information.

[0028] For example, if the status information of each structure of a steel-concrete composite column during construction is compared and analyzed with the status information of each structure of a standard steel-concrete composite column, and it is found that the number of positioning bars in the steel-concrete composite column during construction is greater than the number of positioning bars in the standard steel-concrete composite column, then the number of positioning bars is the information on the increased number of structural elements.

[0029] For example, if the status information of each structure of a steel-concrete composite column during construction is compared and analyzed with the status information of each structure of a standard steel-concrete composite column, and it is found that the number of tie bars in the steel-concrete composite column during construction is less than the number of tie bars in the standard steel-concrete composite column, then the number of tie bars is missing structural quantity information.

[0030] For example, if the condition information of the interconnection between various structures of a steel-concrete composite column during construction is compared and analyzed with the condition information of the interconnection between various structures of a standard steel-concrete composite column, and the number of weld points between tie bars and positioning bars is consistent, then the weld points between tie bars and positioning bars are considered as normal condition information of the structural connection.

[0031] For example, if the condition information of the interconnection between various structures of the steel-concrete composite column during construction is compared and analyzed with the condition information of the interconnection between various structures of the standard steel-concrete composite column, and it is found that the number of weld points between the tie bars and positioning bars in the steel-concrete composite column during construction is the same as that in the standard steel-concrete composite column, then the weld points between the tie bars and positioning bars are considered as the normal condition information of the structural connection.

[0032] For example, by comparing and analyzing the information on the connection points between various structures of a steel-concrete composite column during construction with the information on the connection points between various structures of a standard steel-concrete composite column, it is determined that the number of weld points between tie bars and positioning bars in the steel-concrete composite column during construction is greater than the number of weld points between tie bars and positioning bars in the standard steel-concrete composite column. In this case, the weld points between tie bars and positioning bars are considered beneficial information on the structural connection points.

[0033] For example, if the condition information of the interconnection between various structures of a steel-concrete composite column during construction is compared and analyzed with the condition information of the interconnection between various structures of a standard steel-concrete composite column, and it is found that the number of weld points between the tie bars and positioning bars in the steel-concrete composite column during construction is less than the number of weld points between the tie bars and positioning bars in the standard steel-concrete composite column, then the weld points between the tie bars and positioning bars are considered as harmful condition information of the structural connection.

[0034] The presence of beneficial or harmful physical condition information, increased or missing structural information, beneficial or harmful conditions at structural connections affects the performance of concrete-filled steel tube columns. This allows us to determine whether the performance of the concrete-filled steel tube column is in a normal state. For example, if the thickness of the steel tube at a certain location decreases by 0.1 mm, it will affect the strength performance of the steel tube. Since a large number of tests were conducted during the mechanical analysis process and the test data were compiled into tables, the decrease in steel tube thickness at a certain location by 0.1 mm can be determined by referring to the table to find out how much the strength of the steel tube has decreased.

[0035] Example 2

[0036] Based on Example 1, the following technical features are added: the structural state set is obtained by comparing and analyzing the state information of each structure of the steel-concrete composite column during construction with the state information of each structure of the standard steel-concrete composite column. Specifically, this includes the following steps:

[0037] The status information of each structure of the steel-concrete composite column during construction includes the physical status information of each structure of the steel-concrete composite column during construction and the quantity information of each structure of the steel-concrete composite column during construction.

[0038] The physical state set is obtained by comparing and analyzing the physical state information of each structure of the steel-concrete composite column during construction with the physical state information of each structure of the standard steel-concrete composite column; the physical state set includes normal physical state information, beneficial physical state information and harmful physical state information.

[0039] The quantity information of each structure in the steel-concrete composite column during construction is compared and analyzed with the quantity information of each structure in the standard steel-concrete composite column to obtain a set of structural quantity statuses; the set of structural quantity statuses includes information on the quantity of normal structures, information on the quantity of added structures, and information on the quantity of missing structures;

[0040] The physical state set and the structural quantity state set are combined to form the structural state set.

[0041] The physical state information of each structure of the standard steel-concrete composite column in this application mainly refers to the physical state information of each structure of the steel-concrete composite column under the standard requirements. The quantity information of each structure of the standard steel-concrete composite column in this application mainly refers to the quantity information of each structure of the steel-concrete composite column under the standard requirements.

[0042] Example 3

[0043] Based on Example 2, the following technical features are added: The performance of the concrete-filled steel tube column is comprehensively judged to be in a normal state by considering beneficial physical state information, harmful physical state information, information on increased structural quantity, information on missing structural quantity, beneficial condition information at structural connections, and harmful condition information at structural connections. Specifically, the following steps are included:

[0044] If harmful physical information appears in the steel-concrete composite column during construction, the first performance impact information of the steel-concrete composite column is obtained by analyzing the impact of harmful physical information, beneficial physical state information, increased structural quantity information, and beneficial condition information at structural connections on the performance of the steel-concrete composite column.

[0045] If structural quantity information is missing in the steel-concrete composite column during construction, the impact of missing structural quantity information, beneficial physical state information, increased structural quantity information, and beneficial condition information at structural connections on the performance of the steel-concrete composite column is analyzed to obtain the second performance impact information of the steel-concrete composite column.

[0046] If harmful conditions are found at the structural joints in the concrete-filled steel tube column during construction, the third information on the performance impact of the concrete-filled steel tube column is obtained by analyzing the harmful conditions, beneficial physical conditions, increased structural quantity, and beneficial conditions at the structural joints.

[0047] The performance of the concrete-filled steel tube column is comprehensively assessed by analyzing the performance impact information of the first, second, and third concrete-filled steel tube columns to determine whether the performance of the concrete-filled steel tube column is in a normal state.

[0048] When harmful physical information, missing structural quantity information, or harmful conditions at structural connections appear in a concrete-filled steel tube column during construction, it affects the performance of the column, leading to a decline in performance. Conversely, beneficial physical information, increased structural quantity information, and beneficial conditions at structural connections improve the performance of the concrete-filled steel tube column. Therefore, when harmful physical information, missing structural quantity information, or harmful conditions at structural connections appear in a concrete-filled steel tube column during construction, a comprehensive analysis of the impact of beneficial physical information, increased structural quantity information, and beneficial conditions at structural connections on the performance of the concrete-filled steel tube column is necessary to determine whether the performance of the concrete-filled steel tube column is in a normal state.

[0049] Example 4

[0050] Based on Example 3, the following technical features are added: if a structure with harmful physical information appears in the steel-concrete composite column during construction, the performance impact information of the steel-concrete composite column is obtained by analyzing the harmful physical information, beneficial physical state information, information on the increased number of structures, and beneficial condition information at the structural connection points. Specifically, the following steps are included.

[0051] If a harmful physical information structure appears in the concrete-filled steel tube column during construction, the type of harmful physical information structure and its location in the concrete-filled steel tube column are obtained, as well as the type of harmful physical information structure's adverse effects on the performance of the concrete-filled steel tube column at the corresponding location and the degree of adverse effects on the performance of the concrete-filled steel tube column at the corresponding location are obtained. Among them, the location of the harmful physical information structure in the concrete-filled steel tube column is marked as the location of the first harmful structure, the type of harmful physical information structure's adverse effects on the performance of the concrete-filled steel tube column at the corresponding location is marked as the first harmful effect type, and the degree of adverse effects on the performance of the concrete-filled steel tube column at the corresponding location is marked as the first harmful effect degree value.

[0052] If a structure containing harmful physical information appears in the concrete-tube steel column during construction, it is then determined whether a structure containing beneficial physical information also appears. If a structure containing beneficial physical information does appear, the type of beneficial physical information structure and its location within the concrete-tube steel column are obtained. Furthermore, the type of beneficial physical information structure and its beneficial impact on the performance of the concrete-tube steel column at the corresponding location are determined. Based on the location of the beneficial physical information structure within the concrete-tube steel column and the location of the first harmful structure, the degree of influence of the type of beneficial physical information structure on the performance of the concrete-tube steel column at the location of the first harmful structure is determined. The type of beneficial physical information structure that influences the performance of the concrete-tube steel column at the corresponding location is marked as the first beneficial impact type, and the degree of influence of the type of beneficial physical information structure on the performance of the concrete-tube steel column at the location of the first harmful structure is marked as the first beneficial impact degree value.

[0053] If harmful physical information is found in the steel-concrete composite column during construction, it is determined whether structures with increased structural quantity information are present. If such structures are present, the types and locations of these increased structures within the steel-concrete composite column are obtained. The beneficial effects of these increased structural types on the performance of the steel-concrete composite column at the corresponding location are also determined. Furthermore, based on the location of the increased structural structures within the steel-concrete composite column and the location of the first harmful structure, the degree of influence of the increased structural quantity information on the performance of the steel-concrete composite column at the location of the first harmful structure is assessed. Existing methods can determine the degree of influence of increased structural quantity information on the performance of the steel-concrete composite column at the location of the first harmful structure, such as numerical simulation finite element analysis. A three-dimensional model of the steel-concrete composite column is established using finite element software to accurately simulate the material properties and geometric parameters of the steel tube, concrete, and increased structures. By setting different quantities and locations of increased structures, as well as the location of the first harmful structure, corresponding loads and boundary conditions are applied to the model for numerical calculations. The stress and strain distribution cloud maps at the first harmful structure in the analysis and calculation results were used to extract mechanical data of key parts, such as maximum stress and maximum strain values. The results under different working conditions were compared to quantify the impact of the increased number and location of the added structure on the performance of the steel-concrete composite column at the first harmful structure. Parametric analysis was performed in the finite element model, setting the number and location of the added structure, as well as its relative position to the first harmful structure, as parameters. By changing these parameters and conducting extensive numerical calculations, the performance variation law of the steel-concrete composite column under different parameter combinations was systematically analyzed, and the relationship curves or functions between parameters and performance were established. This allowed for a more comprehensive and in-depth understanding of the impact of the added structure on the performance of the steel-concrete composite column at the first harmful structure in a specific location. Specifically, the beneficial impact of the type of added structure on the performance of the steel-concrete composite column at the corresponding location was marked as the second beneficial impact type, and the degree of influence of the increased structure on the performance of the steel-concrete composite column at the first harmful structure location was marked as the second beneficial impact degree value.

[0054] If beneficial structural connection information appears in the steel-concrete composite column during construction, it is determined whether such beneficial structural connection information exists in the steel-concrete composite column during construction. If beneficial structural connection information does appear, the location of the beneficial structural connection information structure within the steel-concrete composite column is obtained, along with the type of beneficial impact of the beneficial structural connection information on the performance of the steel-concrete composite column at the corresponding location. Furthermore, based on the location of the beneficial structural connection information structure within the steel-concrete composite column and the location of the first harmful structure, the degree of influence of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the location of the first harmful structure is determined. The type of beneficial impact of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the corresponding location is marked as the third beneficial impact type, and the degree of influence of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the location of the first harmful structure is marked as the third beneficial impact degree value.

[0055] Determine whether any of the first, second, and third types of beneficial impacts are the same as the first type of harmful impact;

[0056] If none of the first, second, and third beneficial impact types are the same as the first harmful impact type, then the first harmful impact type is marked as the first harmful performance impact type, and the first harmful impact degree value is marked as the first harmful performance impact degree value.

[0057] If any of the first, second, or third beneficial impact types are the same as the first harmful impact type, then the first comprehensive impact value is calculated by combining the first harmful impact degree value, the first beneficial impact degree value, the second beneficial impact degree value, and the third beneficial impact degree value that have the same type.

[0058] If the first comprehensive impact value is greater than zero, then the first harmful impact type is marked as the first harmful performance impact type, and the first comprehensive impact value is marked as the first harmful performance impact value.

[0059] If the first comprehensive impact value is less than or equal to zero, then there is no first type of harmful impact;

[0060] Among them, the combination of the first type of harmful performance influence and the first degree of harmful performance influence value forms the performance influence status information of the first steel tube concrete column.

[0061] If harmful physical information appears in the concrete-filled steel tube column during construction, such as a reduction in the thickness of the positioning reinforcement (e.g., a decrease in the cross-sectional area of ​​the positioning reinforcement by 0.01 square centimeters), the performance of the concrete-filled steel tube column will decline. In this case, the location of the harmful physical information structure within the concrete-filled steel tube column should be determined. A table should be consulted to obtain the type of harmful physical information structure and the degree of its harmful impact on the performance of the concrete-filled steel tube column at that location. For example, a decrease in the cross-sectional area of ​​the positioning reinforcement by 0.01 square centimeters will affect the strength performance of the concrete-filled steel tube column at that location. The table can be consulted to determine the extent of the decrease in the strength performance of the concrete-filled steel tube column.

[0062] If harmful physical information appears in the steel-concrete composite column during construction, it is necessary to determine whether beneficial physical information, structures with increased structural information, and beneficial conditions at structural connections appear in the steel-concrete composite column during construction. This is because if beneficial physical information, structures with increased structural information, and beneficial conditions at structural connections appear in the steel-concrete composite column during construction, the performance of the steel-concrete composite column will be improved.

[0063] This application determines whether any of the first, second, and third beneficial impacts are the same as the first harmful impact. For example, the first harmful impact may be the strength performance of a concrete-filled steel tube column, the first beneficial impact may be the strength performance of a concrete-filled steel tube column, and the second and third beneficial impacts may both be the stiffness performance of a concrete-filled steel tube column.

[0064] Therefore, if the first type of harmful impact is the same as the first type of beneficial impact, then the first comprehensive impact value is obtained by subtracting the first beneficial impact value from the first harmful impact value. If the first comprehensive impact value is less than or equal to zero, then there is no first type of harmful impact, that is, there is no impact on the strength performance of the steel-concrete composite column. If the first comprehensive impact value is greater than zero, then the first type of harmful impact is marked as the first type of harmful performance impact, and the first comprehensive impact value is marked as the first type of harmful performance impact value.

[0065] Example 5

[0066] Based on Example 4, the following technical feature is added: if structural quantity information is missing in the steel-concrete composite column during construction, the performance impact information of the steel-concrete composite column is obtained by analyzing the effects of missing structural quantity information, beneficial physical state information, increased structural quantity information, and beneficial condition information at structural connections on the performance of the steel-concrete composite column. Specifically, this includes the following steps:

[0067] If structural quantity information is missing in a concrete-filled steel tube column during construction, the following information is obtained: the type of missing structure and its location within the concrete-filled steel tube column. Furthermore, the type of harmful impact of the missing structure on the performance of the concrete-filled steel tube column at the corresponding location is determined, along with the degree of that harmful impact. Specifically, the location of the missing structure within the concrete-filled steel tube column is marked as the location of the second harmful structure; the type of harmful impact of the missing structure on the performance of the concrete-filled steel tube column at the corresponding location is marked as the second harmful impact type; and the degree of harmful impact on the performance of the concrete-filled steel tube column at the corresponding location is marked as the second harmful impact degree value.

[0068] If a structure lacking structural quantity information is found in a concrete-filled steel tube column during construction, it is determined whether a structure with beneficial physical information is present in the column. If such a structure is present, the type and location of the beneficial physical information structure within the column are determined, along with the type of beneficial physical information structure's impact on the performance of the column at the corresponding location. Furthermore, based on the location of the beneficial physical information structure within the column and the location of the first harmful structure, the degree of influence of the beneficial physical information structure type on the performance of the column at the location of the second harmful structure is determined. The type of beneficial physical information structure's impact on the performance of the column at the corresponding location is marked as the fourth beneficial impact type, and the degree of influence of the beneficial physical information structure type on the performance of the column at the location of the second harmful structure is marked as the fourth beneficial impact degree value.

[0069] If harmful physical information is found in the steel-concrete composite column during construction, it is determined whether an increased structural quantity information is present in the steel-concrete composite column during construction. If such an increased structural quantity information is present, the type of increased structural quantity information and its location within the steel-concrete composite column are obtained. Furthermore, the beneficial impact of the increased structural quantity information type on the performance of the steel-concrete composite column at the corresponding location is determined. Based on the location of the increased structural quantity information structure within the steel-concrete composite column and the location of the second harmful structure, the degree of influence of the increased structural quantity information on the performance of the steel-concrete composite column at the location of the second harmful structure is determined. Specifically, the beneficial impact type of the increased structural quantity information type on the performance of the steel-concrete composite column at the corresponding location is marked as the fifth beneficial impact type, and the degree of influence of the increased structural quantity information on the performance of the steel-concrete composite column at the location of the second harmful structure is marked as the fifth beneficial impact degree value.

[0070] If beneficial structural connection information appears in the steel-concrete composite column during construction, it is determined whether such beneficial structural connection information exists in the steel-concrete composite column during construction. If beneficial structural connection information does appear, the location of the beneficial structural connection information structure within the steel-concrete composite column is obtained, along with the type of beneficial impact of the beneficial structural connection information on the performance of the steel-concrete composite column at the corresponding location. Furthermore, based on the location of the beneficial structural connection information structure within the steel-concrete composite column and the location of the second harmful structure, the degree of influence of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the location of the second harmful structure is determined. Specifically, the type of beneficial impact of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the corresponding location is marked as the sixth type of beneficial impact, and the degree of influence of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the location of the second harmful structure is marked as the sixth degree of beneficial impact value.

[0071] The performance impact information of the second steel-concrete composite column is obtained by analyzing and judging the second type of harmful impact, the fourth type of beneficial impact, the fifth type of beneficial impact, the sixth type of beneficial impact, the degree value of the second type of harmful impact, the degree value of the fourth type of beneficial impact, the degree value of the fifth type of beneficial impact, and the degree value of the sixth type of beneficial impact.

[0072] The analysis and judgment of the second type of harmful impact, the fourth type of beneficial impact, the fifth type of beneficial impact, the sixth type of beneficial impact, the degree value of the second type of harmful impact, the degree value of the fourth type of beneficial impact, the degree value of the fifth type of beneficial impact, and the degree value of the sixth type of beneficial impact yields information on the performance impact of the second steel-concrete composite column. This analysis includes the following steps:

[0073] Determine whether any of the fourth, fifth, and sixth beneficial impact categories are identical to the second harmful impact category;

[0074] If none of the fourth, fifth, and sixth beneficial impact categories are the same as the second harmful impact category, then the second harmful impact category is marked as the second harmful performance impact category, and the second harmful impact degree value is marked as the second harmful performance impact degree value.

[0075] If any of the fourth, fifth, or sixth beneficial impact categories are the same as the second harmful impact category, then the second harmful impact degree value, the fourth beneficial impact degree value, the fifth beneficial impact degree value, and the sixth beneficial impact degree value are calculated to obtain the second comprehensive impact degree value.

[0076] If the second comprehensive impact value is greater than zero, then the second harmful impact type is marked as the second harmful performance impact type, and the second comprehensive impact value is marked as the second harmful performance impact value;

[0077] If the second comprehensive impact value is less than or equal to zero, then there is no second type of harmful impact;

[0078] Among them, the combination of the second type of harmful performance influence and the second degree of harmful performance influence value forms the information on the performance influence status of the second steel tube concrete column.

[0079] If structural quantity information is missing in a concrete-filled steel tube column during construction, such as two fewer positioning bars, the performance of the concrete-filled steel tube column will decrease. In this case, the location of the missing structural quantity information in the concrete-filled steel tube column should be obtained. By looking up a table, the type of harmful physical information structure and its harmful impact on the performance of the concrete-filled steel tube column at that location can be obtained, along with the degree of harmful impact. For example, if two fewer positioning bars are found, the strength performance of the concrete-filled steel tube column at that location will be affected. By looking up the table, it can be determined how much the strength performance of the concrete-filled steel tube column has decreased.

[0080] If a steel-concrete composite column lacks structural quantity information during construction, it is necessary to determine whether there are structures with beneficial physical information, structures with increased structural quantity information, and beneficial conditions at structural connections within the steel-concrete composite column during construction. This is because the presence of structures with beneficial physical information, structures with increased structural quantity information, and beneficial conditions at structural connections within the steel-concrete composite column during construction improves the performance of the steel-concrete composite column.

[0081] This application determines whether any of the fourth, fifth, and sixth beneficial impacts are the same as the second harmful impact. For example, the second harmful impact may be the strength performance of the concrete-filled steel tube column, the fourth beneficial impact may be the strength performance of the concrete-filled steel tube column, and the fifth and sixth beneficial impacts may both be the stiffness performance of the concrete-filled steel tube column.

[0082] Therefore, if the second type of harmful impact is the same as the fourth type of beneficial impact, then the second comprehensive impact value is obtained by subtracting the fourth type of beneficial impact value from the second type of harmful impact value. If the second comprehensive impact value is less than or equal to zero, then there is no second type of harmful impact, that is, there is no impact on the strength performance of the steel-concrete composite column. If the second comprehensive impact value is greater than zero, then the second type of harmful impact is marked as the second type of harmful performance impact, and the second comprehensive impact value is marked as the second type of harmful performance impact value.

[0084] Based on Example 5, the following technical feature is added: if harmful conditions at structural joints appear in the concrete-filled steel tube column during construction, the performance impact information of the harmful conditions at structural joints, beneficial physical conditions, increased structural quantity, and beneficial conditions at structural joints on the concrete-filled steel tube column is analyzed to obtain a third performance impact information of the concrete-filled steel tube column. Specifically, this includes the following steps:

[0085] If harmful structural conditions are found at the structural joints of the concrete-filled steel tube column during construction, the following information is obtained: the type of the harmful structural condition at the structural joint, the location of the harmful structural condition at the structural joint within the concrete-filled steel tube column, the type of harmful impact of the type of the harmful structural condition at the structural joint on the performance of the concrete-filled steel tube column at the corresponding location, and the degree of harmful impact on the performance of the concrete-filled steel tube column at the corresponding location. Specifically, the location of the harmful structural condition at the structural joint within the concrete-filled steel tube column is marked as the location of the first harmful structure; the type of harmful impact of the type of the harmful structural condition at the structural joint on the performance of the concrete-filled steel tube column at the corresponding location is marked as the type of harmful impact; and the degree of harmful impact on the performance of the concrete-filled steel tube column at the corresponding location is marked as the degree of harmful impact.

[0086] If harmful structural conditions are found at the structural connections of the concrete-filled steel tube (CFST) column during construction, it is determined whether beneficial physical information is present in the CFST column during construction. If beneficial physical information is present, the type of beneficial physical information structure and its location within the CFST column are obtained. The beneficial impact of each type of beneficial physical information structure on the performance of the CFST column at the corresponding location is also determined. Furthermore, based on the location of the beneficial physical information structure within the CFST column and the location of the third harmful structure, the degree of influence of each type of beneficial physical information structure on the performance of the CFST column at the location of the third harmful structure is determined. The type of beneficial physical information structure that influences the performance of the CFST column at the corresponding location is marked as the seventh beneficial impact type, and the degree of influence of each type of beneficial physical information structure on the performance of the CFST column at the location of the third harmful structure is marked as the seventh beneficial impact degree value.

[0087] If harmful physical information is found in the steel-concrete composite column during construction, it is determined whether there is an increase in the number of structures in the steel-concrete composite column. If so, the types of structures with increased structural quantity and their locations within the steel-concrete composite column are obtained. The beneficial effects of these structures on the performance of the steel-concrete composite column at the corresponding location are also determined. Furthermore, based on the location of the structures with increased structural quantity and their relationship to the location of the third harmful structure, the degree of influence of the increased structural quantity on the performance of the steel-concrete composite column at the location of the third harmful structure is assessed. The beneficial effects of the types of structures with increased structural quantity on the performance of the steel-concrete composite column at the corresponding location are marked as the eighth beneficial effect type, and the degree of influence of the increased structural quantity on the performance of the steel-concrete composite column at the location of the third harmful structure is marked as the eighth beneficial effect degree value.

[0088] If beneficial structural connection information appears in the steel-concrete composite column during construction, it is determined whether such beneficial structural connection information exists in the steel-concrete composite column during construction. If beneficial structural connection information does appear, the location of the beneficial structural connection information structure within the steel-concrete composite column is obtained, along with the type of beneficial impact of the beneficial structural connection information on the performance of the steel-concrete composite column at the corresponding location. Furthermore, based on the location of the beneficial structural connection information structure within the steel-concrete composite column and the location of the third harmful structure, the degree of influence of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the location of the third harmful structure is determined. Among these, the type of beneficial structural connection information structure that has a beneficial impact on the performance of the steel-concrete composite column at the corresponding location is marked as the ninth type of beneficial impact, and the degree of influence of the beneficial structural connection information structure on the performance of the steel-concrete composite column at the location of the third harmful structure is marked as the ninth degree of beneficial impact value.

[0089] The performance impact information of the third type of harmful impact, the seventh type of beneficial impact, the eighth type of beneficial impact, the ninth type of beneficial impact, the degree value of the third type of harmful impact, the degree value of the seventh type of beneficial impact, the degree value of the eighth type of beneficial impact, and the degree value of the ninth type of beneficial impact are analyzed and judged to obtain the performance impact information of the third type of steel tube concrete column.

[0090] The analysis and judgment of the third type of harmful impact, the seventh type of beneficial impact, the eighth type of beneficial impact, the ninth type of beneficial impact, the degree value of the third type of harmful impact, the degree value of the seventh type of beneficial impact, the degree value of the eighth type of beneficial impact, and the degree value of the ninth type of beneficial impact yields information on the performance impact of the third type of steel-concrete composite column. This analysis includes the following steps:

[0091] Determine whether any of the seventh, eighth, or ninth beneficial impact categories are the same as the third harmful impact category;

[0092] If none of the seventh, eighth, or ninth beneficial impact categories are the same as the third harmful impact category, then the third harmful impact category will be marked as the third harmful performance impact category, and the third harmful impact degree value will be marked as the third harmful performance impact degree value.

[0093] If any of the seventh, eighth, or ninth beneficial impact categories are the same as the third harmful impact category, then the third comprehensive impact value is calculated by combining the seventh, eighth, and ninth beneficial impact values.

[0094] If the third comprehensive impact value is greater than zero, then the third harmful impact type is marked as the third harmful performance impact type, and the third comprehensive impact value is marked as the third harmful performance impact value.

[0095] If the third comprehensive impact value is less than or equal to zero, then there is no third type of harmful impact;

[0096] Among them, the combination of the type of third harmful performance impact and the degree of third harmful performance impact forms the information on the performance impact of the second steel-concrete composite column.

[0097] If harmful conditions are found at structural connections in a concrete-filled steel tube column during construction, such as two fewer weld points between the positioning bars and tie bars, the performance of the concrete-filled steel tube column will decrease. In this case, the location of the harmful conditions at the structural connections in the concrete-filled steel tube column should be obtained. By referring to a table, the type and degree of harmful impact of the harmful conditions on the performance of the concrete-filled steel tube column at that location can be determined. For example, if two fewer weld points are found between the positioning bars and tie bars, the strength performance of the concrete-filled steel tube column at that location will be affected. By referring to the table, the extent to which the strength performance of the concrete-filled steel tube column has decreased can be determined.

[0098] If harmful structural conditions are found at the structural joints of a concrete-filled steel tube column during construction, it is necessary to determine whether beneficial physical conditions, increased structural information, and beneficial structural joint conditions are present in the concrete-filled steel tube column during construction. This is because the presence of beneficial physical conditions, increased structural information, and beneficial structural joint conditions in the concrete-filled steel tube column during construction improves the performance of the concrete-filled steel tube column.

[0099] This application determines whether any of the seventh, eighth, and ninth beneficial impacts are the same as the third harmful impact. For example, the third harmful impact is the strength performance of the concrete-filled steel tube column, the seventh beneficial impact is the strength performance of the concrete-filled steel tube column, and the eighth and ninth beneficial impacts are both the stiffness performance of the concrete-filled steel tube column.

[0100] Therefore, if the third type of harmful impact is the same as the seventh type of beneficial impact, then the third comprehensive impact value is obtained by subtracting the seventh type of beneficial impact value from the third type of harmful impact value. If the third comprehensive impact value is less than or equal to zero, then there is no third type of harmful impact, that is, there is no impact on the strength performance of the steel-concrete composite column. If the third comprehensive impact value is greater than zero, then the third type of harmful impact is marked as the third type of harmful performance impact, and the third comprehensive impact value is marked as the third type of harmful performance impact value.

[0101] Example 7

[0102] Based on Example 6, the following technical features are added: The performance of the steel-concrete composite column is comprehensively judged based on the performance impact information of the first, second, and third steel-concrete composite columns. Specifically, this includes the following steps:

[0103] Determine whether the types of the first, second, and third hazardous performance effects are the same;

[0104] If the types of the first, second, and third harmful performance effects are different, then the values ​​of the degree of the first, second, and third harmful performance effects shall be calculated separately, and the values ​​of the degree of the first, second, and third harmful performance effects shall be compared with the corresponding thresholds to determine whether the performance of the concrete-filled steel tube column is in a normal state.

[0105] If harmful physical information, missing structural quantity information, and harmful condition information at structural connections are found in the concrete-filled steel tube column during construction, the types of the first, second, and third harmful performance impacts are statistically analyzed to determine if they are the same. If they are different, the severity values ​​of the first, second, and third harmful performance impacts are calculated separately. These values ​​are then compared with corresponding thresholds to determine if the performance of the concrete-filled steel tube column is normal. If the severity value of the first harmful performance impact exceeds the preset threshold, then... If the first type of harmful performance impact on the performance of the concrete-filled steel tube column is in an abnormal state, and the second type of harmful performance impact exceeds the preset threshold, then the second type of harmful performance impact on the performance of the concrete-filled steel tube column is judged to be in an abnormal state. If the third type of harmful performance impact exceeds the preset threshold, then the third type of harmful performance impact on the performance of the concrete-filled steel tube column is judged to be in an abnormal state. The thresholds for the first, second, and third types of harmful performance impact are all derived from experiments. This is because sometimes, although the value of the first type of harmful performance impact on the concrete-filled steel tube column decreases, it does not affect the normal use of the concrete-filled steel tube column, which indicates that the performance of the concrete-filled steel tube column is in a normal state.

[0106] If there are two identical types of the first, second, and third hazardous performance impact categories, then the two identical categories will be labeled as the first identical hazardous performance impact category and the second identical hazardous performance impact category, respectively. The remaining categories will be labeled as different hazardous performance impact categories. The degree of influence of the different hazardous performance impact categories on the performance of the concrete-filled steel tube column will be labeled as the degree of influence value. The location of the first identical hazardous performance impact category in the concrete-filled steel tube column will be labeled as the first identical hazardous performance impact location, and the location of the second identical hazardous performance impact category in the concrete-filled steel tube column will be labeled as the second identical hazardous performance impact location. The degree of influence of the first identical harmful performance location on the performance of the concrete-filled steel tube column is marked as the first identical harmful performance influence degree value. The degree of influence of the second identical harmful performance type on the performance of the concrete-filled steel tube column at the second identical harmful performance location is marked as the second identical harmful performance influence degree value. Based on the second identical harmful performance influence location and the first identical harmful performance influence location, the degree of harmful influence of the second identical harmful performance type on the performance of the concrete-filled steel tube column at the first identical harmful performance influence location is determined to obtain the first radiation harmful performance influence degree value. Based on the first identical harmful performance influence location and the second identical harmful performance influence location, the degree of harmful influence of the first identical harmful performance type on the performance of the concrete-filled steel tube column at the second identical harmful performance influence location is determined to obtain the second radiation harmful performance influence degree value.

[0107] The first cumulative harmful performance influence value of the first identical harmful performance is obtained by summing the first harmful performance influence value of the first identical harmful performance location;

[0108] The second cumulative harmful performance influence value of the second identical harmful performance is obtained by summing the second identical harmful performance influence value and the second radiation harmful performance influence value;

[0109] The first cumulative harmful performance impact value, the second cumulative harmful performance impact value, and the difference harmful performance impact value are compared with the corresponding thresholds to determine whether the performance of the concrete-filled steel tube column is in a normal state.

[0110] If harmful physical information, missing structural quantity information, and harmful condition information at structural connections are found in the concrete-filled steel tube column during construction, the first, second, and third types of harmful performance impact are statistically analyzed to determine if they are the same. If two of these three types are identical, the degree values ​​of the first identical harmful performance impact, the first radiation-induced harmful performance impact, the second identical harmful performance impact, and the second radiation-induced harmful performance impact are calculated separately. The first identical harmful performance impact and the first radiation-induced harmful performance impact are summed to obtain the first cumulative harmful performance impact value for the location of the first identical harmful performance impact; the second identical harmful performance impact and the second radiation-induced harmful performance impact are summed to obtain the second cumulative harmful performance impact value for the location of the second identical harmful performance impact. The first cumulative harmful performance impact value, the second cumulative harmful performance impact value, and the difference in harmful performance impact value are compared with the corresponding thresholds to determine whether the performance of the concrete-filled steel tube column is in a normal state.

[0111] If the first cumulative harmful performance impact value exceeds the preset first cumulative harmful performance impact threshold, the performance of the concrete-filled steel tube column is judged to be in an abnormal state. If the second cumulative harmful performance impact value exceeds the preset second cumulative harmful performance impact threshold, the performance of the concrete-filled steel tube column is judged to be in an abnormal state. If the difference between the first and third cumulative harmful performance impact values ​​exceeds the preset difference between the first and third cumulative harmful performance impact thresholds, the performance of the concrete-filled steel tube column is judged to be in an abnormal state. The first, second, and third cumulative harmful performance impact thresholds are all derived from experiments. Sometimes, although the first cumulative harmful performance impact value of the concrete-filled steel tube column decreases, it does not affect the normal use of the concrete-filled steel tube column, which indicates that the performance of the concrete-filled steel tube column is in a normal state.

[0112] If the first, second, and third types of harmful performance effects are all the same, the degree of influence of the second harmful performance effect on the performance of the concrete-filled steel tube column at the location of the first harmful structure is marked as the first radiation harmful performance effect degree value; the degree of influence of the third harmful performance effect on the performance of the concrete-filled steel tube column at the location of the first harmful structure is marked as the second radiation harmful performance effect degree value; the degree of influence of the first harmful performance effect on the performance of the concrete-filled steel tube column at the location of the second harmful structure is marked as the third radiation harmful performance effect degree value; the degree of influence of the first harmful performance effect on the performance of the concrete-filled steel tube column at the location of the second harmful structure is marked as the fourth radiation harmful performance effect degree value; the degree of influence of the first harmful performance effect on the performance of the concrete-filled steel tube column at the location of the third harmful structure is marked as the fifth radiation harmful performance effect degree value; and the degree of influence of the second harmful performance effect on the performance of the concrete-filled steel tube column at the location of the third harmful structure is marked as the sixth radiation harmful performance effect degree value.

[0113] The first cumulative harmful performance influence value at the location of the first harmful structure is obtained by summing the first harmful performance influence value, the first radiation harmful performance influence value, and the second radiation harmful performance influence value.

[0114] The second cumulative harmful performance influence value at the location of the second harmful structure is obtained by summing the second harmful performance influence value, the fourth radiation harmful performance influence value, and the third radiation harmful performance influence value.

[0115] The third cumulative harmful performance influence value at the location of the third harmful structure is obtained by summing the third harmful performance influence value, the fifth radiation harmful performance influence value, and the sixth radiation harmful performance influence value.

[0116] The first cumulative harmful performance impact value, the second cumulative harmful performance impact value, and the difference harmful performance impact value are compared with the corresponding thresholds to determine whether the performance of the concrete-filled steel tube column is in a normal state.

[0117] If, during construction, harmful physical information, missing structural quantity information, and harmful condition information at structural connections are found in the steel-concrete composite column, then the types of the first, second, and third harmful performance impacts are statistically analyzed to determine if they are the same. If all three types are the same, then the degree values ​​of the first, second, and third harmful performance impacts, as well as the degree values ​​of the first, second, third, and fourth harmful performance impacts, are calculated separately. The degree values ​​of the third, fifth, and sixth harmful performance impacts are then calculated. The first, second, and third harmful performance impacts are summed to obtain the first cumulative harmful performance impact value at the location of the first harmful structure; the second, third, and fourth harmful performance impacts are summed to obtain the second cumulative harmful performance impact value at the location of the second harmful structure; and the third, fourth, and sixth harmful performance impacts are summed to obtain the second cumulative harmful performance impact value at the location of the second harmful structure. The fifth and sixth radiation hazard impact values ​​are summed to obtain the third cumulative hazard impact value at the location of the third hazard structure. The first, second, and third cumulative hazard impact values ​​are then compared with corresponding thresholds to determine whether the performance of the concrete-filled steel tube column is in a normal state. If the first cumulative hazard impact value exceeds the preset first cumulative hazard impact threshold, the performance of the concrete-filled steel tube column is determined to be in an abnormal state; if the second cumulative hazard impact value exceeds the preset second cumulative hazard impact threshold, the performance is determined to be in an abnormal state. If the cumulative harmful performance impact threshold is reached, the performance of the concrete-filled steel tube column is judged to be in an abnormal state. If the third cumulative harmful performance impact value exceeds the preset third cumulative harmful performance impact threshold, the performance of the concrete-filled steel tube column is judged to be in an abnormal state. The first, second, and third cumulative harmful performance impact thresholds are all derived from experiments. Sometimes, although the first cumulative harmful performance impact threshold of the concrete-filled steel tube column decreases, it does not affect the normal use of the concrete-filled steel tube column, which indicates that the performance of the concrete-filled steel tube column is in a normal state.
