摘要
为探究不同结构形式的装配式地铁车站在地震动作用下的地震响应,以广州地区典型装配式结构车站为背景,对车站结构进行了二维时程分析抗震计算,对比分析了不同形式车站结构在不同地震动下的内力响应及结构变形。结果表明:无柱横向受力箱梁和有柱横向受力板的地铁车站结构在采用铰接节点及固接节点时的层间位移均满足抗震要求,其中无柱车站结构的顶板在E3地震作用下的损伤区域及损伤程度都较大,是抗震的薄弱环节。车站铰接节点附近区域结构的损伤程度比固接节点附近的结构要小,这说明地下车站结构需要具有一定的变形能力。
In order to investigate the seismic response of different structural forms of assembled metro stations under ground shaking,two-dimensional time-time analysis seismic calculations were carried out on a metro station structure in Guangzhou,and the internal force response and structural deformation of different forms of station structures under different ground shaking were compared and analysed.The results show that the interstorey displacements of the two forms of metro station structures discussed in this paper(column-less transverse stressed box beam and column-loaded transverse stressed slab)meet the seismic requirements when hinged and fixed nodes are used,with the top slab of the column-less station structure showing a greater damage area and degree of damage under E3 seismic action,which is the weak link in seismic resistance.The damage to the structure in the area near the articulated nodes of the station is less than that in the area near the solid nodes,which indicates that the underground station structure needs to have a certain deformation capacity.
