[摘要]  大悬挑或大跨度高层结构在竖向地震作用下的结构响应较为明显。针对某裙楼悬挑的B级高度高层建筑，考虑三向地震时程作用，对结构进行多向地震作用下的动力弹塑性时程分析，并对其抗震性能进行评估，结果表明，结构整体抗震性能较好，各构件性能水准均能满足性能设计要求。

Abstract: It is obvious of the response for the long span high structure and cantilever structure under the vertical earthquake. Considering three directions earthquake action as for a B grade high arclutecture with a long cantilever podium structure, the structure aseismic performance is analyzed by the dynanuc elasto-plastic history analysis method. The result is that it is good performance for the whole structure indexes, and the key structure element state can satisfy the performance design requirement.
