［摘要］针对上海某一超限高层加固工程，采用了ETABS和ABAQUS软件对结构进行了动力弹塑性分析比较，结果表明软件建立的模型是可靠的，动力特性、基底剪力、层间位移角和顶点位移等结构主要指标满足设计要求。对框架柱、剪力墙、转换柱和转换桁架等关键构件进行了抗震性能评估，结果表明，在罕遇地震作用下，整体结构能满足“大震不倒”设计要求。

Abstract:The dynamic elastoplastic analysis and comparison were carried out by using ETABS and ABAQUS software for super high-rise strengthening project in Shanghai. The results show that the models built by the softwares are reliable, and the main structural indexes such as dynamic characteristics, base shear force, interlayer displacement angle and vertex displacement meet the design requirements. The seismic performance evaluation was conducted of the key components such as frame column, shear wall, conversion column and conversion truss. The results show that the whole structure can meet the design requirement of “not collapse under rare earthquakes”.
