摘　　要：对招商局广场办公楼超高层结构采用非线性程序ABAQUS进行弹塑性时程分析,该结构首层层高20.65m,外框柱自首层至11层外倾2.23°,11层至顶层内倾1.27°,从26层起核心筒Y向退缩3m。根据结构的顶点位移、层间位移角、基底剪力、钢材塑性应变和壳单元损伤等计算结果,找出结构的薄弱位置,分析罕遇地震下结构的抗震性能,为抗震设计提供依据。ABAQUS software is adopted to execute nonlinear time-history analysis for the Merchants Square high-rise structure with 20.65m height of 1F.Perimeter columns incline outward 2.23°from 1F to 11F and incline inward 1.27°from 11F to the top.The core tube structure of Y direction decrease by 3m form the 26F to the top.Based on the vertex displacement of the structure,story drift,base shear,plastic strain of steel and damage of shear element,the weak parts is defined and seismic performance is analyzed under strong earthquake,which can be referred to the seismic design.

关 键 词：弹塑性时程分析 薄弱部位 性能分析
