（同濟(jì)大學(xué)建筑設(shè)計(jì)研究院（集團(tuán)）有限公司，上海 200092）［摘要］東吳文化中心2#樓為采用鋼筋混凝土框架-剪力墻結(jié)構(gòu)的超限多層建筑，由于結(jié)構(gòu)分塔、連體情況復(fù)雜，樓板不連續(xù)，使得結(jié)構(gòu)多項(xiàng)平面、立面不規(guī)則，造成結(jié)構(gòu)超限。通過調(diào)整結(jié)構(gòu)整體剛度、提高關(guān)鍵構(gòu)件抗震性能目標(biāo)，并進(jìn)行抗震性能化設(shè)計(jì)和靜力彈塑性分析以及適當(dāng)?shù)臉?gòu)造措施，解決了結(jié)構(gòu)超限、大開洞、超長、大跨桁架等難題，使得結(jié)構(gòu)滿足抗震設(shè)防要求。［關(guān)鍵詞］超限多層建筑; 超長結(jié)構(gòu); 抗震性能化設(shè)計(jì)中圖分類號：TU318.2 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2014)22-0021-04Structural analysis and design of Dongwu Culture Center No.2 buildingZheng Hongzhi(Tongji Architectural Design (Group) Co., Ltd., Shanghai 200092, China)Abstract: Dongwu Culture Center No.2 building is a out-of-code multi-story RC frame-shearwall building. The structure has irregularities in plan and elevation due to multi-towers, connectingbody and discontinuous floors. The structural overall rigidity was adjusted and performancebased seismic design objectives of key components were developed. Meanwhile, Pushover analysis on overall structure was carried out for suitable seismic design details. The challenges of out-of-code items, large opening, super-long structure and large-span truss were solved to make the overall structure fulfill relevant seismic precautionary requirements.Keywords: out-of-code multi-story building; super-long structure; performance-based seismic design作者簡介：鄭鴻志，博士，工程師，Email:zheng_hongzhi@sina.com。參考文獻(xiàn)［1］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.［2］江蘇省房屋建筑工程抗震設(shè)防審查細(xì)則［S］. 南京：江蘇省建設(shè)廳，2007.［3］JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京：中國建筑工業(yè)出版社，2011.［4］GB 50009—2012 建筑結(jié)構(gòu)荷載規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2012.
