Finite Element Analysis of the Precast Shear Walls

Abstract:

To reduce the construction cost of the domestic promotion of the new prefabricated concrete shear wall structure system which is promoted in our country. To analyze the factors which can affect the load-carrying capacity and seismic performance of shear wall, including the axial compression ratio, the concrete strength, the reinforcement ratio and some other factors. Among all these factors, the axial compression ratio is the main factor influencing the seismic performance and the section ductility [1]. This paper adopts the ANSYS finite element analysis program, operating a nonlinear analysis on the performance of the precast shear wall when it is with one-way loading, studying the axial compression ratio's effect on the bearing capacity and deformability of the precast shear wall. According to the finite element analysis, when the axial compression ratio is between 0.2 to 0.4 and as it rises, the specimen's bearing capacity and stiffness will increases while deformability and ductility will decrease. Through the finite element analysis, we can provide reliable theory basis for the performance of the precast shear wall when it is with one-way loading.
