Seismic performance analysis of prefabricated building shear wall structures based on finite element analysis

In order to promote the vigorous development of prefabricated building field and improve the seismic performance of its shear wall structure, the seismic performance analysis method of prefabricated building shear wall structures based on finite element is proposed. First, complete the production of prefabricated building shear wall structural specimens, and then establish the standard layer of the structure using floor assembly modelling algorithms. Conduct in-depth analysis of the constitutive relationship of concrete in prefabricated building shear wall structures under cyclic loads, and explore their response forces. The experimental results show that both crack distributions are X-shaped intersecting oblique cracks, with similar failure modes. And when the ductility coefficients of specimens S3 similar to S5 are 6.00, 5.88, and 5.80, respectively, the ductility coefficients of each specimen are relatively large, indicating that this type of shear wall has good deformation ability when the strength specifications of the concrete in the hole are C30, C40, and C50, respectively.
