摘 要:针对北京某地铁车站,根据反应位移法的计算原理,首先求出由土层位移引起作用于地铁车站结构的侧向力、作用于结构周围的剪力及结构惯性力;然后采用Midas GTS有限元软件进行地铁车站的抗震性能分析。由分析结果知,地铁车站层间位移满足规范限值要求,静力工况下的配筋能满足地震工况下的配筋需求,地铁车站结构的配筋控制工况为非地震工况。
Abstract: According to the calculation principle of the response displacement method, the lateral force acting on the metro station structure, the shear force acting on the surrounding structure and the structural inertia force caused by the soil displacement are calculated. The Midas GTS finite element software was used to analyze the seismic performance of the metro station. According to the analysis results, the inter-layer displacement of the metro station can meet the requirements of the standard limit, and the reinforcement under static conditions can meet the reinforcement requirements under seismic conditions. The reinforcement control condition of the metro station structure is non-seismic.
Key words: Metro station; Seismic analysis; Response displacement method; Inter-layer displacement
