[0018] Embodiment 1

[0019] like Figure 1 As shown, the present application provides a method for intelligent arrangement of temporary structural supports based on optimization of structural strain energy, the method comprising:

[0020] Based on the target construction area, obtain design drawings and establish a 3D structural model;

[0021] In modern large-scale and complex projects, temporary support structures during construction are crucial to ensuring the stability of the overall structure and construction safety. With the continuous improvement of building technology and construction requirements, higher requirements are also placed on the accuracy and efficiency of temporary support layout.

[0022] In the embodiment of the present application, the system terminal obtains detailed design drawings according to the specific needs of the target construction area. Subsequently, the three-dimensional structural model is constructed using the design drawings. In this way, the structural characteristics and details of the construction area can be understood more intuitively and comprehensively. This step ensures that the system terminal has a clear and accurate understanding of the construction area, which provides an important basis for subsequent construction planning and temporary support layout.

[0023] Performing structural stress characteristic analysis on the three-dimensional structural model to identify a temporary support point coordinate set;

[0024] In one embodiment, after obtaining the three-dimensional structural model, the system terminal further conducts an in-depth structural stress characteristic analysis. First, the established three-dimensional structural model is preprocessed to clean up insignificant details, repair potential geometric errors, etc., to ensure that the model is suitable for subsequent analysis. Then the processed model is imported into the structural analysis component. After that, the corresponding material properties, such as elastic modulus, Poisson's ratio, density, etc., are defined for each part of the model according to the specific conditions of the construction area. These properties will affect the response of the structure when subjected to force. Then, according to the actual situation of the construction stage, appropriate boundary conditions and loads are applied to the model. Among them, the boundary conditions include fixed support, hinged support, etc., and the loads include deadweight, construction loads, etc. The model is solved using the finite element analysis method to calculate the stress and strain distribution of the structure under given boundary conditions and loads. Finally, the calculation results are analyzed to identify areas with concentrated stress or large deformation. These areas require additional support during the construction process to ensure the stability and safety of the structure. Through the above analysis, the system terminal can accurately identify those key positions that require additional support, that is, temporary support points, and then integrate these temporary support points to obtain a temporary support point coordinate set. In summary, by obtaining a set of temporary support point coordinates, the system terminal can arrange temporary supports more specifically to ensure the smooth progress of the construction process.

[0025] Perform constraint combination based on the temporary support point coordinate set to determine a temporary support point combination solution set;

[0026] In one embodiment, in order to determine the best temporary support arrangement scheme, it is necessary to perform constraint combination analysis based on the identified temporary support point coordinate set. The constraint combination refers to a series of restrictions and combinations on the temporary support point coordinate set according to the engineering requirements and structural characteristics. Based on the identified temporary support point coordinate set, the system terminal reviews the coordinate data of each temporary support point in detail, analyzes its position and role in the overall structure, and evaluates the load-bearing capacity and stability of each support point. Afterwards, the constraints to be followed are determined according to the specific requirements and construction conditions of the project. Among them, the specific requirements of the project include structural stability, construction safety, etc.; the construction conditions include construction space, material supply, etc.; the constraints include stability requirements of the support points, feasibility of the construction stage, and restrictions on the impact on surrounding structures. Then, the system terminal constructs multiple different temporary support point combination schemes based on the formulated constraints and considering the number, position, spacing of the support points and their interaction with the surrounding structures. Finally, the obtained temporary support point combination schemes are organized into a temporary support point combination scheme set. In summary, the whole process is to find a support point combination that meets these conditions under various conditions to ensure the smooth progress of the construction process and provide a basis for subsequent selection and decision-making.

[0027] Performing structural analysis according to the temporary support point combination scheme set, simulating the stress loading conditions during the construction phase, and calculating the structural strain energy, wherein the structural strain energy includes the component stresses corresponding to the multiple temporary support components;

[0028] In one embodiment, in order to evaluate the influence of different temporary support point combination schemes on the structural strain energy and determine the optimal support arrangement scheme, it is necessary to perform structural analysis according to the temporary support point combination scheme set to simulate the stress loading conditions in the construction stage. The stress loading condition refers to the actual action of various stresses and external forces on the structure during the construction process. The structural strain energy refers to the energy generated by deformation of each internal point of the structure when it is subjected to external forces, including the component stress corresponding to multiple temporary support components. The system terminal makes corresponding adjustments to the structural model according to the temporary support point combination scheme determined previously. This includes accurately placing temporary support points in the model and considering their influence on the overall structure. Afterwards, the stress loading conditions in the construction stage are defined. This includes considering factors such as loads, temperature effects, and the role of construction machinery that may be encountered in different construction stages. Each loading condition represents the actual stress conditions that the structure may encounter during the construction process. The structural model is then analyzed under the loading condition to calculate the deformation, stress distribution, and overall stability of the structure under stress loading. During the analysis process, the system terminal evaluates the energy changes caused by deformation inside the structure and calculates the structural strain energy using the objective function. By calculating the structural strain energy, we can understand the energy state of the structure under different loading conditions. On this basis, the system terminal pays special attention to the stress of temporary support components. The stress distribution and size of each support component under different loading conditions are analyzed to ensure that they can withstand the expected stress and to assess whether there is stress concentration or potential safety risks. In summary, this analysis process aims to ensure that the structure can stably and safely withstand various stresses and external forces during the construction phase, providing a solid guarantee for the smooth progress of the project.

[0029] Furthermore, the present application provides a method for performing structural analysis according to the temporary support point combination scheme set, simulating stress loading conditions during the construction phase, and calculating structural strain energy, and the method also includes:

[0030] According to the plurality of temporary support members, the intersection points of N longitudinal and transverse members are used as candidate temporary support points;

[0031] Randomly select M temporary support points from the candidate temporary support points to form a temporary support point combination scheme i (i=1, 2, 3, ..., Z);

[0032] The temporary support point combination scheme i (i=1, 2, 3, ..., Z) is substituted into the objective function to calculate the structural strain energy.

[0033] Preferably, the structural analysis is performed according to the temporary support point combination scheme set, the stress loading conditions in the construction phase are simulated, and the structural strain energy is calculated. The intersection point of the longitudinal and transverse components refers to the node formed by the intersection of the components in the horizontal and vertical directions in the structure. The system terminal first regards the N longitudinal and transverse component intersection points in the structure as potential temporary support points based on the multiple temporary support components that have been determined. These intersection points are usually important nodes for bearing and transmitting forces because they are located in the key parts of the structure. After that, M support points are randomly selected from these alternative temporary support points to form a specific temporary support point combination scheme i. Here i is an integer number, indicating that this is one of many possible combination schemes. In order to evaluate the pros and cons of this temporary support point combination scheme, the system terminal substitutes it into the objective function and calculates the strain energy of the structure under given support conditions. Strain energy is an important indicator for evaluating the stability of a structure, which reflects the change and distribution of the internal energy of the structure when it is subjected to force. By substituting different temporary support point combination schemes into the objective function, the system terminal can calculate the structural strain energy corresponding to each scheme. In this way, the impact of different schemes on structural stability can be compared, so as to screen out those temporary support point combinations that can minimize structural strain energy and improve structural stability. This process helps the system terminal find the optimal temporary support layout plan to ensure the safety and efficiency of the construction process.

[0034] Furthermore, the present application provides the objective function, and the method further comprises:

[0035] The objective function:

[0036]

[0037] Among them, U v is the structural strain energy, if i = 3, then σ x , σ y , σ z , τ xy , τ xz , τ yz is the stress of all temporary support components corresponding to the temporary support point combination scheme i, ε x , ε y , ε z , γ xy , γ xz , γ yz is the strain of all temporary support members corresponding to temporary support point combination scheme i.

[0038] Optionally, the objective function is used to calculate the structural strain energy U v Structural strain energy U vIt is an important indicator to measure the change and distribution of energy inside the structure. It reflects the stress and strain of each point inside the structure when it is subjected to external forces. In this objective function, when the temporary support point combination scheme i is the third scheme, that is, i = 3, σ x , σ y , σ z , τ xy , τ xz , τ yz represents the stress of all temporary support components in this combination scheme. These stress components represent the stress magnitude in different directions, such as σ x represents the normal stress in the x-direction, σ y represents the normal stress in the y direction, σ z represents the normal stress in the z direction, and τ xy , τ xz , τ yz They represent the shear stress on the xy, xz, and yz planes respectively. At the same time, ε x , ε y , ε z , γ xy , γ xz , γ yz It represents the strain of all temporary support components in the temporary support point combination scheme i. These strain components correspond to the stress components and describe the deformation of the structure when subjected to external forces. By substituting these stress and strain components into the objective function, the system terminal can calculate the structural strain energy U under the temporary support point combination scheme v .

[0039] Compare the calculated multiple structural strain energies to determine and select the temporary support point combination scheme with the minimum structural strain energy;

[0040] In one embodiment, the system terminal selects the solutions that meet the actual needs from the temporary support point combination solutions, and compares the structural strain energy calculated by each solution, with the aim of finding the smallest value. This minimum structural strain energy means that under this support solution, the internal energy state of the structure is the most stable, and the deformation and stress distribution are also the most reasonable. Through comparison and screening, the system terminal can determine the temporary support point combination solution with the smallest structural strain energy. This solution will be the best support solution finally selected, because it can minimize the stress concentration and deformation that may occur in the structure during the construction process, thereby ensuring the safety and stability of the structure.

[0041] Furthermore, the present application provides a method for comparing the calculated multiple structural strain energies to determine and select a temporary support point combination scheme with the minimum structural strain energy. Before this, the method also includes:

[0042] Acquire construction demand information of the target construction area, wherein the construction demand information includes a structural stability index and a construction convenience index;

[0043] Based on the construction demand information, the temporary support point combination solution set is filtered to obtain a temporary support point combination alternative solution set.

[0044] Preferably, in order to determine the best temporary support point combination scheme, the system terminal first determines the specific construction requirements of the target construction area. These demand information include the structural stability index and the construction convenience index, which respectively reflect the requirements for structural stability and construction operation convenience during the construction process. The structural stability index is an important indicator to measure the stability of the structure during the construction process. It takes into account factors such as structural stress, deformation, and vibration to ensure that the structure can withstand various external forces and internal stresses during construction and maintain overall stability. The construction convenience index focuses on the convenience and efficiency of construction operations. It takes into account factors such as equipment entry and exit, material transportation, and personnel operation during the construction process to ensure that the construction can proceed smoothly and reduce unnecessary delays and costs. After obtaining these construction demand information, the system terminal filters the previously determined temporary support point combination scheme set. The filtering process is to evaluate the advantages and disadvantages of each temporary support point combination scheme based on the structural stability index and construction convenience index in the construction demand information, and select schemes that can meet the structural stability requirements and ensure the convenience of construction, forming a temporary support point combination alternative scheme set. In this way, the system terminal can select the most suitable set of alternative solutions from a large number of possible temporary support point combinations based on specific construction requirements. These alternative solutions will serve as the basis for subsequent decision-making and optimization to ensure the smooth progress of the construction process and the safety and stability of the structure.

[0045] Furthermore, the present application provides that the construction demand information includes a structural stability index and a construction convenience index, and the method further includes:

[0046] Obtaining load condition information of a target construction area, wherein the load condition information includes dead load condition information, live load condition information, wind load condition information, and earthquake load condition information;

[0047] Acquire component basic parameter information of the plurality of temporary support components, wherein the component basic parameter information includes support position, support form, and support stiffness;

[0048] Optionally, the construction demand information includes a structural stability index and a construction convenience index. The load condition information refers to the conditions and requirements of various external and internal forces borne by the target construction area. These forces include dead loads, live loads, wind loads, and seismic loads. The dead load condition information refers to the loads that remain unchanged for a long time during the use of the structure, such as the dead weight of the structure, the weight of fixed equipment, etc. The live load condition information refers to the loads that will change during use, such as workers, etc. The wind load condition information refers to the loads generated by wind acting on the structure, including wind speed, wind direction, wind pressure distribution, etc. The seismic load condition information refers to the structural vibration and deformation caused by seismic waves, including seismic intensity, seismic wave type, seismic motion parameters, etc. In order to carry out reasonable support design for the target construction area, the system terminal first needs to collect the load condition information of the area. This information includes dead load condition information, live load condition information, wind load condition information, and seismic load condition information. The information on the dead load condition mainly involves the weight of the structure itself and other long-term constant loads, which have a fundamental impact on the structural design; the information on the live load condition considers the loads that may change during the construction process, such as the weight of workers, which is crucial for evaluating the dynamic performance and fatigue life of the structure; the information on the wind load condition focuses on the impact of wind on the structure, especially in high wind speed areas; and the information on the seismic load condition is targeted at seismically active areas to ensure that the structure can remain stable under the action of earthquakes. In addition, in order to evaluate the applicability and performance of different temporary support components, the system terminal also obtains the basic parameter information of these components. These parameters include support position, support form and support stiffness. The support position refers to the specific installation position of the support component in the structure, which is crucial for determining the support effect and construction convenience; the support form describes the structural type and design characteristics of the support component, such as whether beam support, column support, etc. are used; the support stiffness reflects the ability of the support component to resist deformation. The greater the stiffness, the more stable the support effect. In summary, the collection of load condition information and component basic parameter information is to ensure that the temporary support design can accurately reflect the actual construction needs and provide necessary data support for subsequent structural analysis and optimization.

[0049] Based on the basic parameter information of the component and in comparison with the load condition information, the structural stability is evaluated to obtain a structural stability index.

[0050] Optionally, based on the previously acquired component foundation parameter information of multiple temporary support components, the system terminal evaluates the stability of the structure by comparing it with the load condition information of the target construction area. The evaluation process first considers various factors in the load condition information, such as dead load, live load, wind load, and seismic load. Then, these loads are matched and compared with the component foundation parameter information. For example, if the load in a certain area is large, the stiffness of the support component needs to be increased accordingly to provide sufficient support force and reduce structural deformation. At the same time, the selection of support position and support form also needs to be determined according to the distribution and characteristics of the load to ensure the best support effect. Through comparison and analysis, the system terminal obtains an evaluation result on the stability of the structure, namely the structural stability index. This index is a comprehensive indicator that takes into account the response of the structure and the performance of the support components under different load conditions. The higher the structural stability index, the more stable and safe the structure can be under various loads. In summary, based on the comparative evaluation of the component foundation parameter information and the load condition information, the structural stability index can be obtained, so as to understand the structural stability status of the target construction area and provide an important reference for subsequent construction design and decision-making.

[0051] Furthermore, the present application provides a method for evaluating the structural stability based on the basic parameter information of the component and comparing the load condition information to obtain a structural stability index, and the method further includes:

[0052] Based on the basic parameter information of the component, the ratio of the ultimate bearing capacity to the load condition information is calculated to obtain an initialization stability index;

[0053] Optionally, based on the known basic parameter information of the component, such as the support position, support form and support stiffness, the system terminal calculates the ultimate bearing capacity of the temporary support component. The ultimate bearing capacity refers to the maximum force or moment that the support component can withstand under the action of external force, which reflects the strength and stability of the component. At the same time, the system terminal also obtains the load condition information of the target construction area, which includes actual load data such as dead load, live load, wind load and seismic load. Afterwards, in order to quantify the stability performance of the support component relative to the actual load, the system terminal calculates the ratio of the ultimate bearing capacity to a specific load in the load condition information. This ratio is the initialization stability index. The initialization stability index is a quantitative indicator that represents the safety margin of the support component under a specific load. If the initialization stability index is high, it means that the support component has better stability and safety relative to the specific load. By calculating this ratio, the system terminal can more accurately evaluate the performance of the support component under different load conditions and provide a more specific basis for subsequent structural optimization and decision-making.

[0054] Traversing the plurality of temporary support members, calculating the buckling factor of the three-dimensional structural model, and obtaining a first structural stability factor;

[0055] Traversing the plurality of temporary support members, calculating the stiffness degradation degree of the basic parameter information of the members, and obtaining a second structural stability factor;

[0056] Optionally, the buckling factor refers to a parameter used to evaluate the ability of a structure to resist buckling deformation when subjected to external loads. The system terminal examines and analyzes the performance of each supporting member one by one. In this process, two calculations are performed to evaluate the stability of the structure. First, the system terminal uses a static analysis method to calculate the displacement and internal force response of the structure under a given load, and then evaluates the stability of the structure based on these results, and calculates the buckling factor of the three-dimensional structural model to obtain the first structural stability factor. The buckling factor is a key indicator used to measure the ability of a structure to resist buckling deformation when subjected to external loads. By calculating the buckling factor of each temporary supporting member, the system terminal can understand the impact of different support schemes on the overall stability of the structure and provide a basis for selecting the optimal support scheme. Secondly, the stiffness of the member when it is not loaded or under a small load is determined and used as the initial stiffness. Then, the load history borne by the member is defined, including the size of the load, the loading rate, the number of loading times, etc. After determining the initial stiffness and load history, the system terminal cyclically loads the member and calculates the stiffness of the member after each loading cycle. As the number of cycles increases, the stiffness of the component will gradually decrease, which reflects the process of stiffness degradation. Finally, the degree of stiffness degradation is calculated based on the data obtained from the stiffness degradation simulation to obtain the second structural stability factor. The degree of stiffness degradation reflects the degree of reduction in the stiffness performance of the supporting component during the load-bearing process. Stiffness is the ability of a structure to resist deformation, while stiffness degradation means that this ability decreases with time or load. By calculating the degree of stiffness degradation, the system terminal can understand the performance attenuation of the supporting component under different loads, thereby evaluating its impact on the long-term stability of the structure. In summary, by traversing multiple temporary supporting components and calculating the first structural stability factor and the second structural stability factor, the stability of the structure under different support schemes can be comprehensively evaluated. These factors provide the system terminal with quantitative information about the structural performance, helping it to make more correct decisions and ensure the smooth progress of the construction process and the long-term safety and stability of the structure.

[0057] The initialization stability index is checked by using the first structural stability factor and the second structural stability factor to obtain a structural stability index.

[0058] Optionally, after obtaining the two stability factors, the system terminal further analyzes the two stability factors, combines the analysis results with the initial stability index, and performs principal component analysis on the initial evaluation results. By comprehensively considering the impact of the first structural stability factor and the second structural stability factor on structural stability, a more accurate and comprehensive structural stability index can be obtained. This structural stability index will provide the system terminal with a clearer and more quantitative indicator for evaluating the stability of the structure. It not only considers the ability of the structure to resist buckling deformation, but also considers the impact of component stiffness degradation. Through this index, the performance of the structure under different load conditions can be more accurately understood, providing a more reliable basis for subsequent decision-making and optimization.

[0059] Furthermore, the present application provides that the initialization stability index is corrected by the first structural stability factor and the second structural stability factor to obtain the structural stability index, and the method further includes:

[0060] Obtaining a first structural stability parameter by using the first structural stability factor and the initial stiffness of the plurality of temporary support members;

[0061] The second structural stability parameter is obtained by using the second structural stability factor and the instability safety factor;

[0062] Optionally, the system terminal obtains a first structural stability parameter by multiplying the first structural stability factor by the initial stiffness of multiple temporary support members. This parameter reflects an assessment of the overall stability of the structure based on the initial stiffness of the support members, taking into account the ability of the structure to resist buckling deformation. On the other hand, the second structural stability parameter is obtained by multiplying the second structural stability factor by the instability safety factor. This parameter takes into account the stability degradation that may be caused by the stiffness degradation during the long-term use of the structure. The instability safety factor is an indicator used to evaluate the safety of the structure in an unstable state. It is combined with the degree of stiffness degradation to reflect the degree to which the structure can remain stable when the stiffness is reduced. In summary, the first structural stability parameter mainly focuses on the ability of the structure to resist buckling deformation and the initial stiffness of the support members, while the second structural stability parameter focuses on the impact of the structural stiffness degradation on the long-term stability. These two parameters together provide the system terminal with a more comprehensive and in-depth assessment of the stability of the structure, which helps to better understand the performance of the structure at different stages and provide a strong basis for subsequent optimization and decision-making.

[0063] The first structural stability parameter and the second structural stability parameter are used as principal component weights, and the initialized stability index is corrected to obtain a structural stability index.

[0064] Optionally, after obtaining the first structural stability parameter and the second structural stability parameter, the system terminal uses these two parameters as the principal component weights to calibrate the initial stability index. This process is a weighted adjustment of the initial stability index, the purpose of which is to make it more consistent with the stability performance of the structure in actual use. Specifically, the system terminal uses the first structural stability parameter and the second structural stability parameter as weights respectively, and performs weighted summation on the initial stability index. This not only takes into account the ability of the structure to resist buckling deformation and the initial stiffness of the supporting members, but also takes into account the influence of stiffness degradation of the structure during use. In this way, a more accurate and comprehensive structural stability index can be obtained. This index not only takes into account the performance of the structure at different stages, but also combines the influence of multiple stability parameters. It provides us with a clearer and more quantitative indicator for evaluating the stability of the structure and provides a more reliable basis for subsequent decision-making and optimization.

[0065] Temporary support arrangement is carried out through a temporary support point combination scheme with minimal structural strain energy.

[0066] In one embodiment, after the system terminal determines the optimal combination of temporary support points, it performs temporary support layout work. This includes determining the location of the support points, selecting appropriate support materials and structural forms, etc. During the layout process, it is necessary to ensure the stability and reliability of the support points, and to be able to effectively support the structure and reduce deformation and vibration. In summary, temporary support layout is performed through a temporary support point combination scheme with the smallest structural strain energy in order to ensure the stability and safety of the structure during construction or maintenance. By analyzing and calculating the strain energy under different schemes, finding the optimal support point layout method, and performing actual layout work, the stability and safety of the structure can be effectively improved.

[0067] In summary, the embodiments of the present application have at least the following technical effects:

[0068] The embodiment of the present application constructs a three-dimensional structural model according to the design drawings of the target construction area, and deeply analyzes the structural force characteristics of the model to determine the potential temporary support point coordinate set. Subsequently, based on these coordinate sets, a variety of possible temporary support point combination schemes are generated. Next, in order to evaluate the applicability of each combination scheme, the structural strain energy under each scheme is calculated in detail by simulating the stress loading conditions in the construction stage, which includes the stress state of all temporary support components. After completing the structural strain energy calculation of all schemes, the temporary support point combination scheme with the smallest strain energy is screened out by comparative analysis as the optimal solution. In addition, in order to ensure the safety and efficiency of construction, construction demand information, such as structural stability index and construction convenience index, is also considered to screen and optimize the temporary support point combination scheme. When evaluating the structural stability, the method comprehensively considers the load condition information and the basic parameter information of the temporary support component, such as support position, form and stiffness. Finally, through this series of analysis and calculation, the method provides a scientific and reasonable temporary support arrangement scheme for structural construction. These technical effects jointly solve the technical problem of excessive stress and strain in the temporary support process of the structure to ensure construction safety.
