The structure has features such as multiple irregularities, height over B-level requirement of the code, large base podium without joints and 35m-span cantilever in northwest part. The characteristics of towers, podium and mutual relations were introduced in perspective of structural system. Performance-based structural design, temperature effect analysis for the large base podium and large-span cantilever analysis were carried out according to the project characteristics. Integral performance-based analysis shows that the structure can reach respected performance goals and seismic performances of the single tower and double towers are similar. Results of nonlinear analysis under temperature action and gravity load show that parts with large stress mainly distribute in large-span bearings and towers, which should be appropriately strengthened. Finite element analysis results show that the supporting column transfer truss with the herringbone shape can meet the requirements of carrying capacity and normal operating condition.Keywords: performance-based design; temperature effect; nonlinear analysis; cantilever作者簡(jiǎn)介：王興法，總工程師，教授級(jí)高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email：xingfa.wang@vip.sina.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］廣東省建筑科學(xué)研究院. 深圳灣科技生態(tài)城四標(biāo)段風(fēng)致結(jié)構(gòu)荷載分析報(bào)告［R］. 2012.［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(guó)建筑工業(yè)出版社，2011.［4］林超偉，王興法，汪洋，等. 某特別不規(guī)則的框支剪力墻結(jié)構(gòu)抗震性能設(shè)計(jì)［J］. 建筑結(jié)構(gòu)，2012，42（S2):270-273.［5］香港華藝設(shè)計(jì)顧問(wèn)（深圳）有限公司. 深圳灣科技生態(tài)園四區(qū)結(jié)構(gòu)超限高層抗震設(shè)計(jì)可行性論證報(bào)告 ［R］.2012.［6］林超偉，王興法，陳勤，等.長(zhǎng)富金茂大廈混凝土收縮徐變分析及結(jié)構(gòu)設(shè)計(jì)［J］. 建筑結(jié)構(gòu)，2011，41(5):43-45,59.［7］CEB-FIP Model Code 1990 Design code:comite eurointernational du beton［S］.
