[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0051] In the description of the embodiments of the present invention, "a plurality of" means at least two.

[0052] Example 1: In order to prevent cracks in large-volume concrete structures due to shrinkage and temperature changes, it is necessary to accurately understand the temperature stress of the entire structure. In order to fill the gap in the current stress calculation of large-volume reinforced concrete special-shaped structures, this embodiment provides a stress calculation method for large-volume reinforced concrete special-shaped structures, such as Figure 1 As shown, the following specific steps are included:

[0053] S1, dividing the special-shaped reinforced concrete structure into regions according to the structural data of the special-shaped reinforced concrete structure to obtain a plurality of sub-regions constituting the special-shaped reinforced concrete structure.

[0054] Among them, the structural data of the special-shaped reinforced concrete structure can be obtained by establishing a three-dimensional model corresponding to the special-shaped reinforced concrete structure, which can include three-dimensional point cloud data, and the three-dimensional point cloud data can clearly show the angles between each plane in the structure, the size of each plane, the height of each plane, etc.

[0055] Optionally, the above-mentioned area division is specifically as follows:

[0056] S11, obtaining a structural plate of a special-shaped reinforced concrete structure from the structural data. The structural plate can be considered as an entire plane, that is, judged by the outer wall of each plate. For a single plate, its outer wall should be a plane, or the inclination angle between the multiple surfaces constituting the plane does not exceed a threshold, which may be 5°.

[0057] S12, dividing each structural plate into six side plate categories according to position.

[0058] Among them, the six side faces can be used to split the special-shaped reinforced concrete structure into 6 parts according to the six views, and each structural plate on each side of the six views can be classified into the corresponding plate category; such as a special-shaped reinforced concrete structure with a spherical structure, its six views are six arc surfaces, and there are overlapping parts in its six views. In actual implementation, they can be deleted so that the six views that constitute the spherical structure can just be spliced ​​together to form this spherical structure.

[0059] S13 , for structural plates in the same plate category, the structural plates whose angles with each other do not exceed a threshold are divided into the same sub-area according to the position height of each structural plate.

[0060] Specifically, after the structural plates are divided, multiple spaced structural plates may be included in the same sub-area. This situation will not affect the subsequent calculation of temperature difference, elastic modulus, and stress. Of course, if the steel bar ratios of the multiple structural plates included in the same sub-area are different, which will lead to errors in the calculation of temperature difference and elastic modulus, the multiple structural plates will need to be divided into sub-areas again.

[0061] S2, performing boundary constraint classification on each sub-region and obtaining constraint classification results for each sub-region, wherein the constraint classification results include fixed constraints and incomplete constraints.

[0062] Among them, boundary constraints are classified for each sub-region. The purpose of this is to find the area where stress will affect its structure, so as to calculate the stress and perform subsequent processing on this area. For areas where stress will not affect its area, stress-related analysis is not performed. For example, in a sub-region of a quadrilateral structure, when there is blocking concrete on each side of the quadrilateral, the area can be divided into fixed constraints. For multiple structural plates in a sub-region, each structural plate needs to be classified, and finally the structural plates are retained as fixed constraints.

[0063] S3, for each sub-region whose constraint classification result is a fixed constraint, obtain the comprehensive temperature difference of each sub-region, where the comprehensive temperature difference includes the day-night temperature difference and the seasonal temperature difference.

[0064] The temperature difference is the difference in temperature obtained at different time periods. The above comprehensive temperature difference is obtained by the following method:

[0065] S31 , dividing the sub-region into a central region and an edge region, and obtaining the central temperature and the edge temperature respectively.

[0066] S32, calculating the comprehensive temperature of the sub-region using the middle temperature and the edge temperature.

[0067] Optionally, the above comprehensive temperature is specifically:

[0068] ,in: ;

[0069] Where, represents the integrated temperature, represents the weight of the middle area, Indicates the middle temperature, represents the edge temperature, represents the weight of edge temperature, represents the temperature correction amount of the edge area, represents the edge heat flux density; Indicates the area of ​​the exposed edge region, For time, take 24; represents the density of concrete, represents the specific heat capacity of concrete, Represents the volume of the edge area; the weights of the middle area and the edge can be determined by the proportion of the area. For example, the preset size of the edge can be set. For example, for a 4*4 square plane, the edge with a length unit can be identified as the edge part. In this 4*4 plane, the area of ​​the middle area is 3*3=9, and the area of ​​the edge part is 7. The weight of the middle area is 9 / 16, and the area of ​​the edge part is 7 / 16.

[0070] S33, calculating the corresponding comprehensive temperature by obtaining temperature values ​​during the day and night, and obtaining the day and night temperature difference, calculating the corresponding comprehensive temperature by obtaining temperature values ​​in different seasons, and obtaining the seasonal temperature difference.

[0071] S4, using the steel bar parameters and concrete parameters of each sub-region in the special-shaped reinforced concrete structure, obtain the comprehensive elastic modulus of each sub-region at different ages.

[0072] Optionally, the comprehensive elastic modulus of the above sub-regions at different ages is specifically:

[0073] ;

[0074] Where, Indicates age t The comprehensive elastic modulus, represents the elastic modulus of steel bars, represents the total area of ​​the reinforcement in the cross section of the sub-area, represents the total area of ​​concrete in the cross section of the sub-region, Indicates age t The elastic modulus of concrete.

[0075] The elastic modulus of the concrete at different ages is as follows:

[0076] ,in, ;

[0077] Where, Indicates age t The elastic modulus of concrete, represents the empirical coefficient, which is 0.09; Indicates the number of days of age, represents the admixture correction factor, Indicates the corresponding coefficient of fly ash content, Indicates the coefficient corresponding to the slag powder dosage.

[0078] S5, based on the comprehensive temperature difference and comprehensive elastic modulus of each sub-region whose constraint classification result is fixed constraint, determine the structural stress of each sub-region at different ages.

[0079] Specifically, the structural stresses of the above sub-regions at different ages are as follows:

[0081] Where, Indicates that the sub-region is in the age t The structural stress, Indicates age t The comprehensive elastic modulus, represents the expansion coefficient of concrete, Indicates the temperature difference between day and night or seasonal temperature difference, represents the relaxation coefficient of concrete, Represents the constraint coefficient.

[0082] In this embodiment, first, the structure of the special-shaped reinforced concrete is divided into multiple sub-regions according to its appearance, and boundary constraint classification is performed on each sub-region. The purpose is to find the area where stress will affect its structure, so as to calculate the stress and subsequently process the area. For the area where stress will not affect its area, stress correlation analysis is not performed; secondly, the constraint classification results are sub-regions with fixed constraints, and the comprehensive temperature difference of each sub-region and the comprehensive elastic modulus at different ages are calculated; finally, the structural stress of the corresponding sub-region is calculated based on the comprehensive temperature difference and comprehensive elastic modulus of each sub-region; and the structural stress of each sub-region obtained can provide a reference for the application of prestress.

[0083] Specifically, by dividing the structure of the special-shaped structure and calculating the structural stress of each sub-region separately, the stress judgment of the special-shaped structure as a whole has the advantage of being more accurate; when calculating the comprehensive temperature, the different temperature changes in different regions are taken into account, and the weights of each region are added to calculate the comprehensive temperature of the entire region, and then the comprehensive temperature difference is obtained through the comprehensive temperature, so that the calculation of the temperature difference is more accurate; when calculating the elastic modulus of the reinforced concrete as a whole, the elastic modulus of the overall structure is obtained by the elastic modulus of the steel bar unit and the elastic modulus of the concrete unit, and the influence of the steel bar on the concrete is comprehensively considered to accurately analyze and calculate the stress value of the reinforced concrete.

[0092] Among them, in the third module, the comprehensive temperature difference is obtained by the following method:
