Description

Technical Field

[0001] The present invention relates to the technical field of architectural design, and particularly to an automatic beam reinforcement design method based on a reinforcement tendency table. Background Art

[0002] In architectural engineering, the reinforcement drawing of structural beams is the part that consumes the most manpower in structural design, mainly reflected in the large workload and the lack of a fixed design method. There are many reinforcement points in the single-layer reinforcement of beam reinforcement drawings. For ordinary projects, there are about 1000 reinforcement points in a single layer, and the number of reinforcement points in a single layer of a large basement can reach tens of thousands. There are many code provisions related to beam reinforcement in the structural code. At different reinforcement points, there are different code conditions, and multiple code conditions need to be considered simultaneously for each reinforcement point. Moreover, for each reinforcement point of the beam, there are multiple feasible reinforcement schemes according to the layout of surrounding components. The advantages and disadvantages of each reinforcement scheme depend on the experience and subjective judgment of engineers and are difficult to be accurately quantified. Therefore, traditional programmed reinforcement generally can only be based on a certain specific rule and it is difficult to find the most suitable reinforcement scheme among multiple reinforcement schemes. Designers need to make a large number of modifications after the reinforcement drawing completed by the program, which is time-consuming and laborious. Summary of the Invention

[0003] The present invention provides an automatic beam reinforcement design method based on a reinforcement tendency table. By sorting out the beam reinforcement tendency and parameter conditions, the reinforcement tendency under different design conditions is clearly listed in a table, and the beam uses this reinforcement tendency table for reinforcement design, so as to obtain an automatic beam reinforcement design result that fully meets the design requirements.

[0004] The present invention is realized through the following technical solutions:

[0005] An automatic beam reinforcement design method based on a reinforcement tendency table, characterized by comprising:

[0006] S1. Formulate a reinforcement tendency table, and the reinforcement tendency details under different design conditions are included in the reinforcement tendency table;

[0007] S2. On the basis of the existing reinforcement area result, automatically design a reinforcement scheme corresponding to the reinforcement area through the reinforcement tendency table.

[0008] As an optimization, the reinforcement tendency table includes a specific bar selection tendency table and a general reinforcement tendency table. Among them, the specific bar selection tendency table includes the longitudinal bar reinforcement tendency table for seismic beams, the through-length bar tendency table for seismic beams, the longitudinal bar reinforcement tendency table for non-seismic beams, the stirrup reinforcement tendency table for beams, and the waist bar reinforcement tendency table for beams; the general reinforcement tendency table includes the preferred diameter table for beam longitudinal bars and the minimum number table for beam longitudinal bars.

[0009] As an optimization, the general longitudinal bar tendency table of the aseismic beam includes the first general longitudinal bar tendency table of the aseismic beam with "no consideration of avoiding wall column bars on both sides", the second general longitudinal bar tendency table of the aseismic beam with "only unilateral consideration of avoiding wall column bars", and the third general longitudinal bar tendency table of the aseismic beam with "considering avoiding wall column bars on both sides". The parameters in the first general longitudinal bar tendency table, the second general longitudinal bar tendency table, and the third general longitudinal bar tendency table of the aseismic beam all include the beam width and the reinforcement area. The results filled in the first general longitudinal bar tendency table, the second general longitudinal bar tendency table, and the third general longitudinal bar tendency table of the aseismic beam are the general longitudinal bar diameters under the combination of the beam width and the reinforcement area. The longitudinal bar reinforcement tendency table of the aseismic beam includes the upper longitudinal bar reinforcement tendency table of the aseismic beam and the lower longitudinal bar reinforcement tendency table of the aseismic beam. The upper longitudinal bar reinforcement tendency table of the aseismic beam includes the first upper longitudinal bar reinforcement tendency table of the aseismic beam with "no consideration of avoiding wall column bars on both sides", the second upper longitudinal bar reinforcement tendency table of the aseismic beam with "only unilateral consideration of avoiding wall column bars", and the third upper longitudinal bar tendency table of the aseismic beam with "considering avoiding wall column bars on both sides". The lower longitudinal bar reinforcement tendency table of the aseismic beam includes the first lower longitudinal bar reinforcement tendency table of the aseismic beam with "no consideration of avoiding wall column bars on both sides", the second lower longitudinal bar reinforcement tendency table of the aseismic beam with "only unilateral consideration of avoiding wall column bars", and the third lower longitudinal bar tendency table of the aseismic beam with "considering avoiding wall column bars on both sides".

[0010] As an optimization, the parameters in the first upper longitudinal bar reinforcement tendency table, the second upper longitudinal bar reinforcement tendency table, and the third upper longitudinal bar tendency table of the aseismic beam all include the beam width, the reinforcement area, and the diameter of the continuous bar. The results filled in the first upper longitudinal bar reinforcement tendency table, the second upper longitudinal bar reinforcement tendency table, and the third upper longitudinal bar tendency table of the aseismic beam are the suitable reinforcement results under the combination of the three parameters of the beam width, the reinforcement area, and the general longitudinal bar diameter of the aseismic beam. The parameters in the first lower longitudinal bar reinforcement tendency table, the second lower longitudinal bar reinforcement tendency table, and the third lower longitudinal bar tendency table of the aseismic beam all include the beam width and the calculated reinforcement value. The results filled in the first lower longitudinal bar reinforcement tendency table, the second lower longitudinal bar reinforcement tendency table, and the third lower longitudinal bar tendency table of the aseismic beam are the suitable reinforcement results under the combination of the two parameters of the beam width and the calculated reinforcement value of the aseismic beam.

[0011] As an optimization, the longitudinal bar reinforcement tendency table of the non-aseismic beam includes the upper longitudinal bar tendency table of the non-aseismic beam and the lower longitudinal bar tendency table of the non-aseismic beam. The parameters in the upper longitudinal bar tendency table of the non-aseismic beam and the lower longitudinal bar tendency table of the non-aseismic beam all include the beam width and the reinforcement area. The results filled in the upper longitudinal bar tendency table of the non-aseismic beam and the lower longitudinal bar tendency table of the non-aseismic beam are the suitable reinforcement results under the combination of the beam width and the reinforcement area of the non-aseismic beam.

[0012] As an optimization, the beam stirrup reinforcement tendency table is used to specify the minimum stirrup diameter allowed for beams in different height ranges. The parameters of the beam stirrup reinforcement tendency table include the minimum stirrup diameter, the applicable minimum beam height, the applicable maximum beam height, the applicable minimum beam width, and the applicable maximum beam width.

[0013] As an optimization, the parameters of the beam waist reinforcement tendency table include the web height and the beam width. The results filled in the beam waist reinforcement tendency table are the appropriate number of structural waist reinforcements and the corresponding minimum waist reinforcement diameter under the combination of the web height and the beam width.

[0014] As an optimization, the beam longitudinal reinforcement preferred diameter table is used for the situation when the beam width, the reinforcement area, and the diameter of the continuous longitudinal reinforcement exceed the seismic beam longitudinal reinforcement tendency table and the non-seismic beam longitudinal reinforcement tendency table. The parameters of the beam longitudinal reinforcement preferred diameter table include the reinforcement area and the beam width, and the results in the beam longitudinal reinforcement preferred diameter table are the longitudinal reinforcement diameters under the combination of the reinforcement area and the beam width. By specifying the preferred diameters under different design conditions, it clarifies the direction for program reinforcement (after determining the longitudinal reinforcement diameter, the program calculates the number of longitudinal reinforcements according to the reinforcement area to complete the reinforcement), and the reinforcement area in the beam longitudinal reinforcement preferred diameter table can be expanded as needed to meet customer requirements.

[0015] As an optimization, the beam minimum longitudinal reinforcement number table is used for the situation when the beam width, the reinforcement area, and the diameter of the continuous longitudinal reinforcement exceed the seismic beam longitudinal reinforcement tendency table and the non-seismic beam longitudinal reinforcement tendency table, and is used to define the minimum number of longitudinal reinforcements for beams of different widths.

[0016] As an optimization, the specific implementation steps of S2 are as follows:

[0017] S2.1. For the upper reinforcement of seismic beams, combine all the seismic beams connected in a straight line into a beam string, summarize all the reinforcement points of the upper reinforcement bars of the beam string, select the type of the seismic beam upper reinforcement tendency table according to the type of the seismic beam, determine the alternative values of the diameter of the continuous longitudinal reinforcement at each reinforcement point through the seismic beam continuous longitudinal reinforcement tendency table, and then take the alternative value of the diameter of the continuous longitudinal reinforcement that appears the most at each reinforcement point as the diameter of the continuous longitudinal reinforcement of the entire beam string. At this time, if the beam width, the reinforcement area, and the diameter of the continuous longitudinal reinforcement do not exceed the seismic beam longitudinal reinforcement tendency table, then determine the reinforcement result of each reinforcement point according to the determined diameter of the continuous longitudinal reinforcement in combination with the seismic beam upper reinforcement tendency table; if the beam width, the reinforcement area, and the diameter of the continuous longitudinal reinforcement are not within the coverage range of the seismic beam upper reinforcement tendency table, then determine the preferred diameter of the beam according to the beam width and the reinforcement area through the longitudinal reinforcement preferred diameter table, and then perform reinforcement according to the determined preferred diameter of the beam;

[0018] S2.2. For the upper reinforcement bars of non-seismic beams, if the beam width and reinforcement area are within the coverage of the upper reinforcement bar tendency table for non-seismic beams, directly select from the upper reinforcement bar tendency table for non-seismic beams; if the beam width and reinforcement area are not within the coverage of the upper reinforcement bar tendency table for non-seismic beams, determine the preferred diameter of the beam through the longitudinal bar preferred diameter table based on the beam width and reinforcement area, and then perform reinforcement according to the determined preferred diameter of the beam;

[0020] S2.4. For the lower reinforcement bars of non-seismic beams, if the beam width and reinforcement area are within the coverage of the lower reinforcement bar reinforcement tendency table for non-seismic beams, directly select from the lower reinforcement bar reinforcement tendency table for non-seismic beams; if the beam width and reinforcement area are not within the coverage of the lower reinforcement bar reinforcement tendency table for non-seismic beams, determine the preferred diameter of the beam through the longitudinal bar preferred diameter table based on the beam width and reinforcement area, and then perform reinforcement according to the determined preferred diameter of the beam;

[0021] S2.5. For the beam stirrups, if the beam height and width are within the coverage of the stirrup reinforcement tendency table, directly select the minimum stirrup diameter from the stirrup reinforcement tendency table, and calculate the stirrup spacing d corresponding to the selected diameter according to the stirrup reinforcement value.

[0022] If the stirrup spacing d is greater than b mm, take the stirrup spacing value as b; if the calculated stirrup spacing d ∈ [a, b], then this stirrup spacing is the calculated actual value; if the calculated stirrup spacing is less than a mm, increase the stirrup diameter by one grade, recalculate the stirrup spacing corresponding to the increased stirrup diameter by one grade and then make a judgment; if the beam height and width are not within the coverage of the stirrup reinforcement tendency table, take the stirrup diameter as c, calculate the stirrup spacing d corresponding to the selected diameter according to the stirrup reinforcement value, if the stirrup spacing d is greater than b mm, take the stirrup spacing value as b, if the calculated stirrup spacing d ∈ [a, b], then this stirrup spacing is the calculated actual value, if the calculated stirrup spacing is less than a mm, increase the stirrup diameter by one grade, recalculate the stirrup spacing corresponding to the increased stirrup diameter by one grade and then make a judgment.

[0034] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the embodiments and the drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and do not limit the present invention.

[0035] Embodiment

[0036] A method for automatically designing beam reinforcement based on a reinforcement tendency table, characterized by including:

[0037] S1. Develop a reinforcement tendency table, which includes the details of reinforcement tendencies under different design conditions.

[0038] S2. Based on the existing reinforcement areas, use the reinforcement tendency table to automatically design a reinforcement plan corresponding to the reinforcement areas. The existing reinforcement calculation areas specifically include the longitudinal bar calculation area, the stirrup calculation area, and the waist bar calculation area. The reinforcement plan specifically includes the corresponding longitudinal bar diameter and number, stirrup diameter and spacing, and waist bar diameter and number.

[0039] In this embodiment, the reinforcement tendency table includes a specific bar selection tendency table and a general reinforcement tendency table. Among them, the specific bar selection tendency table includes the longitudinal bar reinforcement tendency table for seismic beams, the full-length bar tendency table for seismic beams, the longitudinal bar reinforcement tendency table for non-seismic beams, the stirrup reinforcement tendency table for beams, and the waist bar reinforcement tendency table for beams; the general reinforcement tendency table includes the preferred diameter table for beam longitudinal bars and the minimum number table for beam longitudinal bars.

[0040] Among them, the longitudinal bar reinforcement tendency table for seismic beams is used to specify the longitudinal bar reinforcement plan for seismic beams under different beam sections and different beam reinforcement calculation results. The full-length bar tendency table for seismic beams is used to specify the full-length bar diameter under the combination of beam width and reinforcement area. The longitudinal bar reinforcement tendency table for non-seismic beams is used to specify the longitudinal bar reinforcement plan for non-seismic beams under different beam sections and different beam reinforcement calculation results. The stirrup reinforcement tendency table for beams is used to specify the minimum diameter of stirrups for beams under different beam sections. The waist bar reinforcement tendency table for beams is used to specify the number and minimum diameter of waist bars for beams under different beam sections.

[0041] In this embodiment, the full-length bar tendency table for seismic beams includes the first full-length bar tendency table for seismic beams with "no consideration of avoiding wall column bars on both sides", the second full-length bar tendency table for seismic beams with "only unilateral consideration of avoiding wall column bars", and the third full-length bar tendency table for seismic beams with "consideration of avoiding wall column bars on both sides"; the parameters in the first full-length bar tendency table for seismic beams, the second full-length bar tendency table for seismic beams, and the third full-length bar tendency table for seismic beams all include the beam width and the reinforcement area, and the results filled in the tables of the first full-length bar tendency table for seismic beams, the second full-length bar tendency table for seismic beams, and the third full-length bar tendency table for seismic beams are the full-length bar diameters under the combination of beam width and reinforcement area.

[0042] In this embodiment, the longitudinal reinforcement tendency table of the seismic beam includes the longitudinal reinforcement tendency table of the upper part of the seismic beam and the longitudinal reinforcement tendency table of the lower part of the seismic beam. The longitudinal reinforcement tendency table of the upper part of the seismic beam includes the first longitudinal reinforcement tendency table of the upper part of the seismic beam with "no consideration of avoiding wall column reinforcement on both sides", the second longitudinal reinforcement tendency table of the upper part of the seismic beam with "only unilateral consideration of avoiding wall column reinforcement", and the third longitudinal reinforcement tendency table of the upper part of the seismic beam with "consideration of avoiding wall column reinforcement on both sides"; the longitudinal reinforcement tendency table of the lower part of the seismic beam includes the first longitudinal reinforcement tendency table of the lower part of the seismic beam with "no consideration of avoiding wall column reinforcement on both sides", the second longitudinal reinforcement tendency table of the lower part of the seismic beam with "only unilateral consideration of avoiding wall column reinforcement", and the third longitudinal reinforcement tendency table of the lower part of the seismic beam with "consideration of avoiding wall column reinforcement on both sides".

[0043] In this embodiment, the parameters of the first longitudinal reinforcement tendency table of the upper part of the seismic beam, the second longitudinal reinforcement tendency table of the upper part of the seismic beam, and the third longitudinal reinforcement tendency table of the upper part of the seismic beam all include the beam width, the reinforcement area, and the diameter of the continuous reinforcement. The results filled in the first longitudinal reinforcement tendency table of the upper part of the seismic beam, the second longitudinal reinforcement tendency table of the upper part of the seismic beam, and the third longitudinal reinforcement tendency table of the upper part of the seismic beam are the appropriate reinforcement results under the combination of the three parameters of the beam width, the reinforcement area, and the diameter of the continuous reinforcement of the seismic beam; the parameters of the first longitudinal reinforcement tendency table of the lower part of the seismic beam, the second longitudinal reinforcement tendency table of the lower part of the seismic beam, and the third longitudinal reinforcement tendency table of the lower part of the seismic beam all include the beam width and the calculated reinforcement value. The results filled in the first longitudinal reinforcement tendency table of the lower part of the seismic beam, the second longitudinal reinforcement tendency table of the lower part of the seismic beam, and the third longitudinal reinforcement tendency table of the lower part of the seismic beam are the appropriate reinforcement results under the combination of the two parameters of the beam width and the calculated reinforcement value of the seismic beam. It should be noted that the reinforcement result here refers to the reinforcement area value given by the structural calculation, the selection of the steel bar diameter and the number of bars (including the combination of steel bars with different diameters). The following reinforcement results are the same as those here.

[0044] As shown in Figure 1, Figure 1(a) is an example diagram of the longitudinal reinforcement tendency table of the lower part of the beam of the longitudinal reinforcement tendency table of the seismic beam (only unilateral consideration of avoiding column and wall reinforcement).

[0045] The longitudinal reinforcement tendency table of the seismic beam is divided into two categories: the longitudinal reinforcement of the upper part of the beam and the longitudinal reinforcement of the lower part of the beam. Each category is further divided into three types, namely: no consideration of avoiding wall column reinforcement on both sides, only unilateral consideration of avoiding wall column reinforcement, and consideration of avoiding wall column reinforcement on both sides, for a total of six forms. The parameter items of the longitudinal reinforcement tendency table of the seismic beam include the beam width, the reinforcement area, and the diameter of the continuous reinforcement. The user fills in the appropriate reinforcement results under each option combination according to the above three options. Among them, the beam width ranges from 150 to 700 mm, the reinforcement area ranges from 0 to 40 cm 2 , and the options for the diameter of the continuous reinforcement include 6 categories: 14, 16, 18, 20, 22, and 25.

[0046] As shown in Figure 1(b), it is an example diagram of the through-length bar inclination table of the seismic-resistant beam (only considering avoiding the column and wall steel bars on one side). The through-length bar inclination table of the seismic-resistant beam is classified into three types, namely: not considering avoiding the column and wall steel bars on both sides, only considering avoiding the column and wall steel bars on one side, and considering avoiding the column and wall steel bars on both sides. The parameters included in the through-length bar inclination table of the seismic-resistant beam all include the beam width and the reinforcement area, and the result filled in the table of the through-length bar inclination table of the seismic-resistant beam is the through-length bar diameter under the combination of the beam width and the reinforcement area.

[0047] As Figure 2(a) and 2(b) shown, it is an example diagram of the longitudinal reinforcement inclination table of the non-seismic beam. In this embodiment, the longitudinal reinforcement inclination table of the non-seismic beam includes the upper reinforcement inclination table 2(a) of the non-seismic beam and the lower reinforcement inclination table 2(b) of the non-seismic beam. The parameters of the upper reinforcement inclination table and the lower reinforcement inclination table of the non-seismic beam both include the beam width and the reinforcement area, and the result filled in the upper reinforcement inclination table and the lower reinforcement inclination table of the non-seismic beam is the suitable reinforcement result under the combination of the beam width and the reinforcement area of the non-seismic beam. The seismic-resistant beam and the non-seismic beam are collected separately because the non-seismic beam does not need to consider whether to avoid the column and wall on both sides. Here, the non-seismic beam generally refers to the secondary beam that is butted against the main beam at the end.

[0048] As Figure 3 shown, it is an example diagram of the beam stirrup reinforcement inclination table. In this embodiment, the beam stirrup reinforcement inclination table is used to specify the minimum stirrup diameter that can be used in different height intervals of the beam, that is, to specify the minimum diameter of the beam stirrup under different beam cross-sections. The parameters of the beam stirrup reinforcement inclination table include the minimum stirrup diameter, the applicable minimum beam height, the applicable maximum beam height, the applicable minimum beam width, and the applicable maximum beam width. Among them, the beam height ranges from 0 to 10000 mm, and the beam width ranges from 150 to 10000 mm. The user can specify the minimum stirrup diameter under different beam height and beam width conditions item by item. The settings of the above parameters can be added or deleted in this table. Based on this, the program calculates the corresponding stirrup spacing according to the calculated value. (The program refers to the structural design program that adopts the reinforcement inclination table proposed by the present invention, such as EasyBIM-S; the calculated value refers to the beam reinforcement area read from the calculation result. On the premise of knowing the stirrup diameter and the reinforcement area, the stirrup spacing can be calculated through simple multiplication and division.) When the stirrup diameter set by the user does not meet the specification and calculation requirements, the specification and calculation shall prevail.

[0049] As Figure 4 shown, it is an example diagram of the beam waist reinforcement inclination table. In this embodiment, the parameters of the beam waist reinforcement inclination table include the web height and the beam width, and the result filled in the beam waist reinforcement inclination table is the appropriate number of structural waist reinforcement bars and the corresponding minimum waist reinforcement diameter under the combination of the waist plate height and the beam width.

[0050] When calculating the height of the beam web, the floor slab thickness is uniformly deducted by 100 mm. When torsion-resistant web reinforcement needs to be configured, the value of the torsion-resistant web reinforcement is not less than that of the structural web reinforcement. At the same time, Figure 4 the table in

[0051] is the number of bars of the structural web reinforcement on one side of the beam, and the structural web reinforcement is symmetrically arranged on both sides of the beam. Figure 5 As shown in

[0052] is an example diagram of the preferred diameter table of the beam longitudinal reinforcement. In this embodiment, the preferred diameter table of the beam longitudinal reinforcement is used when the beam width, reinforcement area, and diameter of the continuous longitudinal reinforcement exceed the seismic beam longitudinal reinforcement reinforcement tendency table and the non-seismic beam longitudinal reinforcement reinforcement tendency table. The parameters of the preferred diameter table of the beam longitudinal reinforcement include the reinforcement area and the beam width, and the result in the preferred diameter table of the beam longitudinal reinforcement is the longitudinal reinforcement diameter under the combination of the reinforcement area and the beam width. By specifying the preferred diameters under different design conditions, the direction for program reinforcement is clarified, and the reinforcement area of the preferred diameter table of the beam longitudinal reinforcement can be expanded as needed to meet customer requirements. Figure 6 As shown in

[0053] is an example diagram of the minimum number of bars of the beam longitudinal reinforcement. In this embodiment, the minimum number of bars of the beam longitudinal reinforcement is used when the beam width, reinforcement area, and diameter of the continuous longitudinal reinforcement exceed the seismic beam longitudinal reinforcement reinforcement tendency table and the non-seismic beam longitudinal reinforcement reinforcement tendency table, and is used to define the minimum number of bars of the longitudinal reinforcement of beams with different widths.

[0054] Finally, the specific implementation steps of the typical S2 are introduced as follows:

[0054] S2.1. For the upper reinforcement of the seismic beam, all the seismic beams connected in a straight line are combined into a beam string, and all the reinforcement points of the upper reinforcement of the beam string are summarized. According to the type of the seismic beam, the type of the seismic beam upper reinforcement reinforcement tendency table is selected. Through the seismic beam continuous longitudinal reinforcement tendency table, the alternative values of the continuous longitudinal reinforcement diameter at each reinforcement point are determined. Then, the alternative value of the continuous longitudinal reinforcement diameter that appears most frequently at each reinforcement point is used as the continuous longitudinal reinforcement diameter of the entire beam string. At this time, if the beam width, reinforcement area, and continuous longitudinal reinforcement diameter do not exceed the seismic beam longitudinal reinforcement reinforcement tendency table, the reinforcement result at each reinforcement point is determined according to the determined continuous longitudinal reinforcement diameter in combination with the seismic beam upper reinforcement reinforcement tendency table; if the beam width, reinforcement area, and continuous longitudinal reinforcement diameter are not within the coverage range of the seismic beam upper reinforcement tendency table, the preferred diameter of the beam is determined according to the beam width and the reinforcement area through the preferred diameter table of the longitudinal reinforcement, and then the reinforcement is carried out according to the determined preferred diameter of the beam;

[0055] S2.2. For the upper reinforcement bars of non-seismic beams, if the beam width and the reinforcement area are within the coverage of the upper reinforcement bar inclination table for non-seismic beams, directly select from the upper reinforcement bar inclination table for non-seismic beams; if the beam width and the reinforcement area are not within the coverage of the upper reinforcement bar inclination table for non-seismic beams, determine the preferred diameter of the beam through the longitudinal bar preferred diameter table according to the beam width and the reinforcement area, and then carry out reinforcement according to the determined preferred diameter of the beam; after selecting the preferred diameter, the required number of bars can be calculated based on the calculated reinforcement area (using simple multiplication and division); this is the prior art and will not be elaborated here.

[0056] S2.3. For the lower reinforcement bars of seismic beams, if the beam width and the reinforcement area are within the coverage of the lower reinforcement bar reinforcement inclination table for seismic beams, select the type of the lower reinforcement bar reinforcement inclination table for seismic beams according to the type of the seismic beam, and then directly select from the lower reinforcement bar reinforcement inclination table for seismic beams; if the beam width and the reinforcement area are not within the coverage of the lower reinforcement bar reinforcement inclination table for seismic beams, determine the preferred diameter of the beam through the longitudinal bar preferred diameter table according to the beam width and the reinforcement area, and then carry out reinforcement according to the determined preferred diameter of the beam; after selecting the preferred diameter, the required number of bars can be calculated based on the calculated reinforcement area (using simple multiplication and division); this is the prior art and will not be elaborated here.

[0057] S2.4. For the lower reinforcement bars of non-seismic beams, if the beam width and the reinforcement area are within the coverage of the lower reinforcement bar reinforcement inclination table for non-seismic beams, directly select from the lower reinforcement bar reinforcement inclination table for non-seismic beams; if the beam width and the reinforcement area are not within the coverage of the lower reinforcement bar reinforcement inclination table for non-seismic beams, determine the preferred diameter of the beam through the longitudinal bar preferred diameter table according to the beam width and the reinforcement area, and then carry out reinforcement according to the determined preferred diameter of the beam; after selecting the preferred diameter, the required number of bars can be calculated based on the calculated reinforcement area (using simple multiplication and division); this is the prior art and will not be elaborated here.

[0058] S2.5. For the beam stirrups, if the beam height and width are within the coverage of the stirrup reinforcement inclination table, directly select the minimum stirrup diameter from the stirrup reinforcement inclination table, and calculate the stirrup spacing d corresponding to the selected diameter according to the stirrup reinforcement value (the stirrup reinforcement value is based on the structural calculation result).

[0059] If the stirrup spacing d is greater than b mm, then the stirrup spacing value is taken as b. If the calculated stirrup spacing d ∈ [a, b], then this stirrup spacing is the calculated actual value. If the calculated stirrup spacing is less than a mm, then the stirrup diameter is increased by one grade (the steel bar diameter is a sequence value, not a continuous value, including: 6\8\10\12\14\16\18\20\22\25\28\32... increasing by one grade means being one size larger in the sequence), and recalculate the stirrup spacing corresponding to the increased stirrup diameter and then make a judgment. If the beam height and width are not within the coverage range of the beam stirrup reinforcement tendency table, the stirrup diameter is taken as c. According to the stirrup reinforcement value, calculate the stirrup spacing d corresponding to the selected diameter. If the stirrup spacing d is greater than b mm, then the stirrup spacing value is taken as b. If the calculated stirrup spacing d ∈ [a, b], then this stirrup spacing is the calculated actual value. If the calculated stirrup spacing is less than a mm, then the stirrup diameter is increased by one grade, and recalculate the stirrup spacing corresponding to the increased stirrup diameter and then make a judgment. Here, a is 100, b is 200, and c is 6 (6 is the minimum value specified in the code).

[0060] The present invention collects the user's reinforcement tendency in the form of filling out a table, and forms a reinforcement rule based on the user's reinforcement habit through summarizing and analyzing the table; applies the reinforcement rule to each point where reinforcement is required, and forms a programmed automatic reinforcement that meets the user's reinforcement habit.

[0061] Specifically, based on the existing reinforcement calculation results (including the calculated area of longitudinal bars, the calculated area of stirrups, and the calculated area of waist bars), through the reinforcement tendency table and parameter definition, automatically determine the reinforcement scheme corresponding to the calculated area (including the diameter and number of longitudinal bars, the diameter and spacing of stirrups, and the diameter and number of waist bars).

[0062] In the existing technical solutions, this process is difficult to fully meet the design requirements, and a large amount of manual intervention is required for the automatic decision-making results. After the method proposed by the present invention, it is equivalent to directly letting the user solidify the desired reinforcement scheme into the reinforcement tendency table according to the most detailed situation, so that the reinforcement scheme can maximize the satisfaction of the user's needs, and the automatic decision-making results do not need to be manually modified anymore.

[0063] The above specific implementation manners have further detailed the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above is only the specific implementation manners of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
