# 单层地铁车站结构地震响应分析Seismic Response Analysis of One-Layer Subway Station

Abstract: Three-dimensional numerical simulation calculation model was established based on a practical one-layer subway station. Structure internal forces and deformation were analyzed under static load, middle seismic and large seismic wave excitations. And also, the seismic performance of the structure was evaluated according to code. The analysis results showed that: 1) The column of the subway station is a weak part during earthquake; 2) The internal forces at the combination of side wall and bottom plate were bigger; 3) The existing subway station has good seismic performance and can satisfy the code demands. The research conclusions in the paper can provide references for seismic design and analysis of relevant projections.
