(北京市建筑設(shè)計研究院，北京 100045)［摘要］天津于家堡金融起步區(qū)03-22地塊主樓地上50層，總高214.2m，結(jié)構(gòu)體系為鋼管混凝土框架-鋼筋混凝土核心筒混合結(jié)構(gòu)。為了滿足側(cè)移剛度要求，在層13，26，39設(shè)置了結(jié)構(gòu)加強(qiáng)層。論述了此超高復(fù)雜高層建筑結(jié)構(gòu)的設(shè)計措施和性能目標(biāo)，并對計算結(jié)果列表比較分析。工程初步設(shè)計已通過超限審查。［關(guān)鍵詞］超限高層；鋼管混凝土；混合結(jié)構(gòu)；抗震性能目標(biāo)Design of structure system of Plot 03-22 in Yujiapu Financial District of TangguZhang Yanping, Bao Lei, Lü Suqin, Zhang Bo, Shen Li, Qi Wuhui, Xu Bin(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract:The high-rise office building on Plot 03-22 in Yujiapu Financial District is 2142 meters high on the ground with 50 stories. The building is supported by concrete-filled steel tube frame-RC core system. In order to satisfy the lateral stiffness, horizontal strengthened stories are set at story 13, 26, and 39 According to this out-of-codes and complex high-rise buildings,the design criteria are introduced for the technical measures, earthquake resistance objectives, calculating methods, and the analysis of the results. The priliminary design of this project has already gone through the out-of-codes review.Keywords:out-of-codes high-rise building; concrete-filled steel tube; mixed structure; earthquake resistance objectives作者簡介：張燕平，學(xué)士，高級工程師，Email：zhangyp1117@126.com。參考文獻(xiàn)［1］GB50011—2001建筑抗震設(shè)計規(guī)范(2008年版)［S］.北京：中國建筑工業(yè)出版社，2008.［2］JGJ99—98高層民用建筑鋼結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，1998.［3］JGJ3—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.［4］超限高層建筑工程抗震設(shè)防專項審查技術(shù)要點［S］.［5］劉大海，楊翠如. 型鋼、鋼管混凝土高樓計算和構(gòu)造［M］.北京：中國建筑工業(yè)出版社，2003.
