摘要
针对天津地铁7号线榆关道站工程,基于反应位移法对多遇地震工况下采用SAP84软件建立平面应力模型进行模拟计算分析。基于反应加速度法对罕遇地震工况下采用MIDAS-GTS软件建立平面整体模型进行模拟计算分析。得出了地铁车站在地震作用下的内力和位移地震反应。对现行结构设计进行了校核,分析了结构抗震薄弱部位及地震反应对结构的影响。
According to Yuguan Road station engineering in Tianjin subway,SAP84 software is used to build plane stress model to simulate under frequent earthquake condition based on the response displacement method. And MIDAS-GTS software is used to build plane integral model to simulate under rare earthquake condition based on the response acceleration method. The internal force and displacement of the seismic response under the action of earthquake of subway station is obtained. The existing structural design is checked,and the influence of seismic weak position and seismic response on the structure is analyzed.
