Based on relevant scientific researches, material subroutines were compiled with the concrete constitutive relation considering the constrain effect to simulate the core concrete in concrete filled circular steel tube column accurately. Analysis results show that the calculation results of damage degree based on two programs exist differences but the trends are identical. The maximum elastic-plastic story drift is within the limit of codes. The plastic damage of the structure can meet the requirements of expected performance-based seismic design objectives. The analyses can guide the structural optimization design and weak parts strengthening.Keywords: out-of-code high-rise building; elastic-plastic; performance-based; rare earthquake作者簡介：路江龍，高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，英聯(lián)邦特許結(jié)構(gòu)工程師，Email : Lujianglong@sipdri.com。參考文獻(xiàn)［1］趙變青，談麗華，劉強(qiáng),等.太原國海廣場主樓抗震設(shè)計(jì)與分析［J］. 建筑結(jié)構(gòu)，2014,44(21):36-41.［2］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.［3］GB 50010—2010混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2011.［4］韓林海.鋼管混凝土結(jié)構(gòu)——理論與實(shí)踐［M］. 2版. 北京：科學(xué)出版社，2007.［5］GB 50011—2010建筑抗震設(shè)計(jì)規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2010.
