［摘要］以抗震設(shè)防烈度為8度（0.2g）的某超高層蝶形剪力墻結(jié)構(gòu)為實(shí)例，其結(jié)構(gòu)布置方式采用剪力墻束筒布置。分別選用SATWE,YJK,MIDAS等軟件對(duì)結(jié)構(gòu)進(jìn)行計(jì)算,包括小震抗震分析及彈性時(shí)程分析、中震抗震分析、罕遇地震靜力推覆分析。結(jié)果表明，結(jié)構(gòu)各項(xiàng)指標(biāo)均能滿足規(guī)范要求，能夠?qū)崿F(xiàn)“大震不倒”的抗震設(shè)防目標(biāo)；討論了剪力墻墻肢拉應(yīng)力控制問題，提出在普通結(jié)構(gòu)中將剪力墻拉應(yīng)力控制過嚴(yán)是不合適的。［關(guān)鍵詞］高烈度; 剪力墻結(jié)構(gòu); 蝶形; 超限分析; 墻肢拉應(yīng)力; Pushover分析中圖分類號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
