First of all, the equivalent damping ratio and the number of damping walls were calculated according to the given target displacement. Then the PERFORM-3D program was adopted to perform the time-history analysis under the frequent earthquake level, and the dynamic elasto-plastic analysis under the rare earthquake level as well, both analyses were performed to evaluate the seismic performance of the overall structure. The performance of the critical components was evaluated as well. Meanwhile, the comparative analysis between the energy-dissipated structure and the non-energy-dissipated structure shows that the former structure has capability to undertake greater elasto-plastic deformation and greater strength under rare-earthquakes.Keywords: tall building; energy dissipation; rare-earthquake; dynamic elasto-plastic; performance evaluation作者簡介：戴雅萍，碩士，教授級高級工程師，一級注冊結(jié)構(gòu)工程師，總工程師，Email:yaping.dai@siad-c.com。參考文獻(xiàn)［1］袁雪芬，戴雅萍，張敏，等.宿遷市蘇商大廈超限高層結(jié)構(gòu)設(shè)計(jì)［J］. 建筑結(jié)構(gòu)，2013，43(20): 100-106.［2］南京工業(yè)大學(xué)建筑技術(shù)發(fā)展中心. 宿遷市蘇商大廈結(jié)構(gòu)消能減震分析［R］. 南京，2011.［3］JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京:中國建筑工業(yè)出版社,2011.［4］GB 50011—2001 建筑抗震設(shè)計(jì)規(guī)范［S］. 2008年版. 北京: 中國建筑工業(yè)出版社, 2008.
