An inelastic time history analysis of a complex high-rise building with staggered shear-wall located in Zhuhai was carried out, and the seismic performance under different level earthquakes was studied. Perform-3D program was used to build analysis model and carry out time history analysis. The results were concluded in the entire structure response and the damage information of elements, and quantified the damage degree of this structure under rare earthquake, and verified that this structure would not collapse under rare earthquake.The soft shear floor is not formed in the structure.Keywords: high-rise building; inelastic time history analysis; seismic performance作者简介:王森,博士,高级工程师,Email:ws2001622@163.com。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] 谢靖中,李国强. 错层结构的几点分析[J].建筑科学,2001,17(1):3537.[3] 尹保江,龚思礼,程绍革.高层建筑中错层剪力墙结构的试验研究[J].建筑科学,1999,15(6):1820.[4] Perform-3D user guide version4 [M].CSI.[5] 魏琏.建筑结构抗震设计[M].北京:万国学术出版社,1991.[6] 刘畅,段小廿,魏琏,等.某超限高层结构多程序弹塑性时程分析对比[J].2012,42(11):35-39,18.
