(同濟大學建筑設(shè)計研究院，上海 200092)［摘要］上海國際設(shè)計中心為一呈h形不等高雙塔連體結(jié)構(gòu)，采用鋼框架核心筒結(jié)構(gòu)體系。詳細介紹了該結(jié)構(gòu)分析與設(shè)計的有關(guān)內(nèi)容，包括主、副塔樓結(jié)構(gòu)抗側(cè)力體系、連體結(jié)構(gòu)體系選型與概念設(shè)計、相關(guān)的特殊構(gòu)造措施；并對多遇地震下主副塔結(jié)構(gòu)響應(yīng)的對比分析、連體結(jié)構(gòu)中震分析、副塔傾覆效應(yīng)分析、結(jié)構(gòu)的彈塑性時程分析進行了重點介紹。分析結(jié)果表明，大震作用下，在其他構(gòu)件進入塑性的情況下，連體部位依然保持彈性。［關(guān)鍵詞］連體結(jié)構(gòu)；框架核心筒結(jié)構(gòu)；中震彈性分析；彈塑性時程分析Design of Asymmetry Double-Tower Connected Structure of Shanghai InternationalDesign CenterHe Zhijun,Ding Jiemin,Wu Honglei (Architectural Design and Research Institute of Tongji University,Shanghai 200092,China)Abstract:Shanghai international design center is a h-shape asymmetry double-tower connected structure,which is designed as steel frame-core wall structure. The structural analysis and design are presented,including structural system selection and concept design of lateral resistant system of the dual towers,connected structures and some special seismic fortification measures. The contrast analysis of the single tower structure and dual towers connected structure under frequently occurred earthquake action,moderate earthquake elastic analysis of the connected structure,elasto-plastic dynamic time history analysis of the whole structure under seldom occurred earthquake and overturning action of the minor tower are introduced. Analysis results show that the connected structures remains elastic under the action of seldom occurred earthquake while the other members have turned into inelastic.Keywords:connected structure; frame-core wall structure; elastic/elasto-plastic analysis; moderate earthquake; dynamic time history; analysis作者簡介：何志軍(1972-)，博士，高級工程師，從事大型復雜結(jié)構(gòu)設(shè)計研究。參考文獻［1］高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程(JGJ3—2002)［S］.［2］徐培福，傅學怡，王翠坤，等. 復雜高層建筑結(jié)構(gòu)設(shè)計［M］. 北京：中國建筑工業(yè)出版社，2005.［3］徐培福，等.關(guān)于超限高層建筑抗震設(shè)防審查的若干討論［J］.土木工程學報，2004，37(1).［4］卞朝東,李愛群,婁宇.高層連體結(jié)構(gòu)振型及其參與系數(shù)的分析［J］.建筑科學,2002,18(44).［5］張春濃，徐斌.凱晨廣場多塔連體結(jié)構(gòu)設(shè)計研究［J］.建筑結(jié)構(gòu)，2008，38(1).
