（北京市建筑设计研究院有限公司，北京 100045）［摘要］靖江市文化中心在商业区设置跨度为101.3m的楼面结构，该结构荷载巨大。多个结构方案的比较为大跨度楼面结构设计提供了依据，设计阶段考虑施工过程分析有效消除了拉力支座，简化了支座设计；抗连续性倒塌设计提高了结构的冗余度；舒适度设计为使用人群创造良好的购物环境提供了技术支持；关键节点的计算分析揭示了受力复杂部位的应力分布状态，体现了抗震概念设计的节点强于构件的基本要求；活荷载不均匀布置符合结构概念设计的设计原则。［关键词］大跨度楼面结构; 舒适度; 抗连续性倒塌; 施工过程中图分类号：TU393.3 文献标识码：A 文章编号：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作者简介：秦凯，硕士，高级工程师，Email：1454421@qq.com。参考文献［1］JGJ 3—2010 高层建筑混凝土结构技术规程［S］. 北京：中国建筑工业出版社，2011.［2］GB 50017—2003 钢结构设计规范［S］.北京：中国计划出版社，2003.［3］邱旭光，李东方，姜拥军，等. 钢桁架与钢支撑桁架混凝土筒体连接节点试验研究［J］.建筑结构，2012，42（2）：71-73.［4］陈星，王华林，李娜.广东省博物馆新馆结构设计中的关键技术［J］.建筑结构，2007，37（1）：38-42.
