摘　　要：某工程是存在多项基本不规则项的复杂超高层建筑,文中采用弹塑性动力时程分析法,分析结构在罕遏地震作用下的变形特征、构件内力及剪力墙、连梁、框架柱及框架梁损伤等非线性动力响应;研究结构在罕遇地震作用下的整体抗震性能,找出薄弱部位和构件,为施工图设计中采取有针对性的加强措施来实现"大震不倒"的设防目标提供设计依据。The project is a complex super high-rise building which is irregularity.The thesis adopts incremental dynamic elastic-plastic method to analyze the characters under strong seismic action,and analyzes the nonlinear dynamic response of the shape characters,the internal force of the components and the losses of the shear walls,coupling beams,frame columns and frame beams,simultaneously,studies the structure overall seismic fortification performance,and finds out weak positions and components,and provides design basises in the process of the working drawings design,so that we can adopt certain related pertinency intensive measures to achieve the fortifying purpose of ＇non-collapsed under strong seismic action＇.

关 键 词：超高层建筑 弹塑性动力时程分析 弹塑性位移角 抗震性能目标
