（北京市建筑設計研究院有限公司，北京 100045）［摘要］靖江市文化中心在商業(yè)區(qū)設置跨度為101.3m的樓面結(jié)構(gòu)，該結(jié)構(gòu)荷載巨大。多個結(jié)構(gòu)方案的比較為大跨度樓面結(jié)構(gòu)設計提供了依據(jù)，設計階段考慮施工過程分析有效消除了拉力支座，簡化了支座設計；抗連續(xù)性倒塌設計提高了結(jié)構(gòu)的冗余度；舒適度設計為使用人群創(chuàng)造良好的購物環(huán)境提供了技術(shù)支持；關鍵節(jié)點的計算分析揭示了受力復雜部位的應力分布狀態(tài)，體現(xiàn)了抗震概念設計的節(jié)點強于構(gòu)件的基本要求；活荷載不均勻布置符合結(jié)構(gòu)概念設計的設計原則。［關鍵詞］大跨度樓面結(jié)構(gòu); 舒適度; 抗連續(xù)性倒塌; 施工過程中圖分類號：TU393.3 文獻標識碼：A 文章編號：1002-848X(2014)20-0048-06Structural design of large-span floor structure of Culture Center in JingjiangQin Kai, Zhou Zhongfa, Zhu Zhongyi, Feng Yang, Gao Ming, Li Huafeng, Liang Chenyu, Xue Huili, Deng Xuyang(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: Large-span floor system with span of 101.3m was used in the commercial part of Cultural Center in Jingjiang, and the vertical structure loads are large. The comparison of several structural schemes provided basis for large-span floor structural design. Construction progress was considered in design stage to avoid tension in the connections and simplify the support design. Structural robustness was improved by progressive collapse resistance design. Comfort design provided technical supports for a better shopping environment for users. Analyses of critical joints indicated the complicated stress distribution of the parts and fulfill the basic requirements of seismic conceptual design that joint should be stronger than component. Irregularly distributed variable loads also met the design principle of structural conceptual design.Keywords: large-span floor structure; comfort; progressive collapse resistance; construction process作者簡介：秦凱，碩士，高級工程師，Email：1454421@qq.com。參考文獻［1］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.［2］GB 50017—2003 鋼結(jié)構(gòu)設計規(guī)范［S］.北京：中國計劃出版社，2003.［3］邱旭光，李東方，姜擁軍，等. 鋼桁架與鋼支撐桁架混凝土筒體連接節(jié)點試驗研究［J］.建筑結(jié)構(gòu)，2012，42（2）：71-73.［4］陳星，王華林，李娜.廣東省博物館新館結(jié)構(gòu)設計中的關鍵技術(shù)［J］.建筑結(jié)構(gòu)，2007，37（1）：38-42.
