The main structure has major features of serious deficiencies in the plane floor, ramp floor of large area and the large openings in the east, south and west facade. Comparison and analysis with multi-model using different analysis programs, elastic time-history analysis, dynamic elasticity and plasticity time-history analysis and the seismic function design of the key members were carried out. The results show that the structure has sufficient seismic capacity, inelastic response and failure mechanism can meet the concept of seismic design requirements under rare earthquake.Keywords:complex high-rise building beyond the code limits; deficiencies in the plane floor; openings in the facade; seismic function design; dynamic elasticity and plasticity analysis作者簡介：張敏，教授級高級工程師，一級注冊結(jié)構(gòu)工程師，結(jié)構(gòu)副總工程師，Email:min.zhang@siad.c.com。參考文獻(xiàn)［1］CECS 230:2008高層建筑鋼混凝土混合結(jié)構(gòu)設(shè)計規(guī)程［S］.北京：中國計劃出版社，2008.［2］GB 50011—2001建筑抗震設(shè)計規(guī)范［S］. 2008年版. 北京:中國建筑工業(yè)出版社,2008.［3］同濟(jì)大學(xué)土木工程防災(zāi)國家重點實驗室. 蘇州西交利物浦大學(xué)行政信息樓壓力測量風(fēng)洞試驗研究報告［R］. 2009.［4］JGJ 3—2002 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,2002.［5］南京工業(yè)大學(xué)建筑技術(shù)發(fā)展中心. 蘇州西交利物浦大學(xué)行政信息樓動力彈塑性分析報告［R］. 2010.
