Finite Element Analysis Model Design on the Mechanical Properties of Prefabricated Shear Wall Structure

Abstract

At present, the mechanical properties analysis method of prefabricated shear wall structure based on static test is low overall simulation precision. In this paper, the finite element method is used to analyze the force performance of the prefabricated shear wall structure. Based on the shear of concrete material, elastic modulus, Poisson ratio, open fracture, the transfer coefficients of open and closed fracture, and tensile strength parameters, the finite element model is established by ANSYS. The vertical load and the horizontal load of the prefabricated shear wall structure are calculated, and the limit load value is obtained. The maximum stress change of the connector, the energy dissipation of the shear wall structure, and the change of the equivalent viscous damping coefficient are obtained by the way of loading and displacement change. The experimental results show that the simulated values of stiffness degradation, maximum displacement, maximum strain, and stress distribution obtained by this method are in good agreement with the actual values and are reliable.
