PKPM and ETABS were used for the elastic calculation under minor and moderate earthquake,MIDAS was used for static elastic-plastic analysis under rare earthquake. The vertical discontinuous shear walls and the converted floors were emphatically analyzed. For the weak parts of the whole structure,the flexural capacity and ductility of shear walls were increased to improve the seismic performance. Comprehensive analysis of the results,the gauge design measures are proposed,and the measures to strengthen the structure are put forward.Keywords: exceeding code limit tall building; performance objective; time-history analysis; elastic plastic analysis; seismic performance作者簡介：陳松，博士，高級工程師，一級注冊結(jié)構(gòu)工程師，Email:samboy2006@163.com。參考文獻(xiàn)［1］徐培福, 傅學(xué)怡, 王翠坤, 等．復(fù)雜高層建筑結(jié)構(gòu)設(shè)計［M］.北京：中國建筑工業(yè)出版社, 2005.［2］周穎, 呂西林．中震彈性設(shè)計與中震不屈服設(shè)計的理解及實施［J］.結(jié)構(gòu)工程師，2008，24 (6）：1-5．［3］鄒昀, 呂西林, 錢江．上海環(huán)球金融中心大廈結(jié)構(gòu)抗震性能研究［J］.建筑結(jié)構(gòu)學(xué)報, 2006, 27 (6）：74-80.［4］閻曉銘, 陳察，陳志強(qiáng)，等．空中華西村結(jié)構(gòu)抗震性能研究［J］.建筑結(jié)構(gòu), 2008, 38(8）： 8-13.
