［摘要］采用通用分析软件ABAQUS，通过对一大底盘多塔的高位转换商务公寓的动力弹塑性时程分析，研究了整体结构在大震下的动力响应和关键构件的损伤状况，找出了结构的薄弱位置。分析结果表明：在罕遇地震作用下，结构的最大层间位移角小于规范限值；剪力墙及框架柱的损伤程度除在转换层出现中度损伤外，其他部位均较小；转换梁作为承接上部剪力墙和连接下部框剪结构的关键构件，在地震作用下处于弹性工作阶段。总体来说，本结构在罕遇地震作用下实现了“大震不倒”的抗震性能目标。

Abstract: Though dynamic elastic-plastic time history analysis of the business apartments twin towers building with large podium and a high level transfer floor， by using general analysis software ABAQUS， studied the overall structure models of dynamic response and damage situation of key components， find out the weak position of the structure． Analysis results show that under severe earthquake， the structure of the maximum interlayer displacement angle is less than the standard limit. The damage degree of shear wall and frame column in addition to outside the transformation layer had moderate damage， other parts are lesser； the transfer beam as a key component undertakes upper shear wall and the connection lower frame shear structure， in the stage of flexible work under seismic action． Overall， this structure under severe earthquake is to achieve the seismic performance goals of no collapsing under rare earthquake．

Keywords: twin towers； high level transfer； elastic-plastic time history
