Analysis of Seismic Performance of Prefabricated Seismic Building Wall Based on ANSYS

Abstract

Assembly type buildings is a new form of buildings in our country. It can build quickly and lower cost of production. In order to study the seismic performance of prefabricated structural wall, based on the analysis of the structure composition of the existing seismic wall, through the practical project, Vanke Metropolitan Jinyue Yuan No.6 building, the finite element model of prefabricated wall building was established by ANSYS. The wall unit comprises a wall panel and a lower fixed assembly, a connecting assembly between two wall panels, and a connection limit for two wall panels is implemented by providing a connecting plate. It is analyzed whether the seismic performance of the vibration mode, stress and strain of the new aseismic wall conforms to the requirements of the relevant codes, and further adjustment is made. Using the finite element analysis software, six finite element models with different vibration modes are established and calculated. The failure modes and seismic performance of the models are basically the same as the expected experimental results, which verify the effective seismic performance of the finite element model.
