According to structural seismic conception, performance-based design was given. SATWE and MIDAS were used in seismic calculation under elastic and seismic load. PERFORM-3D was used in elastic-plastic time-history analysis under rare earthquake load, finite element analysis was used for the key point of inclined column and slab stress. The results show that the structure has sufficient seismic capacity and ductility.Keywords: exceed code limits; performance-based design; elastic-plastic time-history analysis; connection strength analysis; slab stress analysis作者简介:冀苗苗,硕士,一级注册结构工程师,Email:beitianzi@163.com。参考文献[1] 韩小雷,陈学伟,林生逸,等. 基于纤维模型的超高层钢筋混凝土结构弹塑性时程分析[J]. 建筑结构,2010,40(2):1316.
