［摘要］采用通用分析軟件ABAQUS，通過對(duì)一大底盤多塔的高位轉(zhuǎn)換商務(wù)公寓的動(dòng)力彈塑性時(shí)程分析，研究了整體結(jié)構(gòu)在大震下的動(dòng)力響應(yīng)和關(guān)鍵構(gòu)件的損傷狀況，找出了結(jié)構(gòu)的薄弱位置。分析結(jié)果表明：在罕遇地震作用下，結(jié)構(gòu)的最大層間位移角小于規(guī)范限值；剪力墻及框架柱的損傷程度除在轉(zhuǎn)換層出現(xiàn)中度損傷外，其他部位均較??；轉(zhuǎn)換梁作為承接上部剪力墻和連接下部框剪結(jié)構(gòu)的關(guān)鍵構(gòu)件，在地震作用下處于彈性工作階段。總體來說，本結(jié)構(gòu)在罕遇地震作用下實(shí)現(xiàn)了“大震不倒”的抗震性能目標(biāo)。

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
