For this reason, structural performance-based seismic design method was conducted. Using two programs, response spectrum analysis of the structure and comparison were conducted, as well as elastic time-history history analysis and the yield analysis under intermediate earthquake using SATWE software. Elastic-plastic time-history analysis of the structure was conducted using PKPM-EPDA software. Based on the characteristics of the structure and analysis results, the structural weak positions were strengthened by some measures, which ensure structural weak parts and important parts not to yield under medium earthquake, and to meet the requirements of elastic-plastic deformation under rare earthquake.Keywords: high-rise building beyond the cold-specification; reinforced concrete shear wall structure; performance-based design; elastic-plastic analysis; strengthening measure作者簡(jiǎn)介：于敬海，博士，研究員，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email: yjh300072@163.com。參考文獻(xiàn)［1］GB 50009—2012 建筑結(jié)構(gòu)荷載規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2012.［2］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2010.［3］JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)程［S］.北京：中國(guó)建筑工業(yè)出版社，2011.［4］中國(guó)建筑科學(xué)研究院PKPMCAD工程部.PUSH&EPDA多層及高層建筑結(jié)構(gòu)彈塑性靜力、動(dòng)力分析軟件用戶(hù)手冊(cè)［M］.北京，2010.［5］曹倩，汪洋，趙 宏.復(fù)雜高層結(jié)構(gòu)體系二道防線的探討［J］.建筑結(jié)構(gòu)，2011,41（S1）:331-335.
