An inelastic time history analysis was carried out on a complex high-rise building located in Shenzhen, and the seismic performance under different level earthquakes was studied in detail. Three computer programs-Perform-3D, ABAQUS, and Ls DYNA were used to build analysis model and carry out time history analysis. The results were concluded in two levels , the entire structure response and the damage information of elements. Detailed results quantified the damage degree of this structure under rare earthquake, and verified that this structure would not collapse under rare earthquake.Keywords: high-rise building; inelastic time history analysis; seismic performance; rare earthquecke作者简介：刘畅，博士，高级工程师，Email:liuchang2@ccdi.com.cn。参考文献［1］ JGJ 3-2002 高层建筑混凝土结构技术规程［S］.北京：中国建筑工业出版社,2002.［2］ Perform 3D user guide version4 ［M］.
