基于反应位移法的地铁车站抗震计算分析

Seismic Analysis of a Subway Station Based on Response Displacement Method

以抗震设防烈度为Ⅶ度,设计基本地震加速度为0.15 g,场地类别为Ⅲ类的地铁车站结构为例,基于反应位移法进行结构的抗震验算,计算中考虑了标准断面和开口断面2种情况。计算结果表明:对于该地铁车站,地震作用影响不明显,其主要控制内力组合为基本组合。

Taking a subway station structure with seismic fortification intensity VII,design basic earthquake acceleration of 0.15 g and site Class III as an example,the seismic checking calculation of the structure is carried out based on Response Displacement Method.Two cases of standard section and open section are considered in the calculation.The results show that the effect of earthquake on the subway station is not obvious,and its main control internal force combination is basic.
