［摘要］以抗震设防烈度为8度（0.2g）的某超高层蝶形剪力墙结构为实例，其结构布置方式采用剪力墙束筒布置。分别选用SATWE,YJK,MIDAS等软件对结构进行计算,包括小震抗震分析及弹性时程分析、中震抗震分析、罕遇地震静力推覆分析。结果表明，结构各项指标均能满足规范要求，能够实现“大震不倒”的抗震设防目标；讨论了剪力墙墙肢拉应力控制问题，提出在普通结构中将剪力墙拉应力控制过严是不合适的。［关键词］高烈度; 剪力墙结构; 蝶形; 超限分析; 墙肢拉应力; Pushover分析中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2016)09-0025-04
Seismic analysis and design for a super high-rise butterfly shear wall structure at seismic district of high intensityLiu Jun1,2, Li Liaobing2, Ji Xun2(1 School of Civil Engineering, Southeast University, Nanjing 210096, China; 2 Taxus Architects Design Co., Ltd., Kunming 650051, China)Abstract: Combined with a super high-rise butterfly shear wall structure with level 8 seismic fortification (0.2g),the concept of shear wall bundle tubes was applied to structure layout. Programs such as SATWE,YJK,MIDAS were used to analyze the structure,including the seismic analysis and the elastic time-history analysis under the frequent earthquake, the seismic analysis under the moderate earthquake, the static Pushover analysis under rare earthquake.The results show that all performances of the structure can meet the requirements of codes,and the seismic performance target of "not collapse under the rare earthquake" can be fulfilled.The control of shear wall limb tension stress was discussed,and the author indicated that it is not appropriate to over-control the shear wall tension stress in the normal structure.Keywords: high intensity; shear wall structure; butterfly; out-of-code analysis; wall tension stress; Pushover analysis
