Seismic Optimization Simulation Analysis of Yi People’s Light Steel-Wood Plastic Residential Structure

Abstract

Through the SAP2000 finite element software, the finite element calculation model of three steel frames for earthquake resistance, base isolation were established for the Xishuangbanna Dai light steel wood-plastic structure. The EI seismic wave was used to analyze the steel frame structure. The acceleration, displacement, natural vibration period and damping effect of the two structural forms under earthquake are compared and analyzed. The research results show that the isolation and shock absorption technology can effectively reduce the impact of earthquake on the structure. Under the comprehensive comparison, the isolation structure with additional Isolation bearing is better than that of the seismic structure.
