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”.

Keywords:super high-rise building;dynamic elastoplastic analysis;strengthening and renovation;seismic performance
