（重庆市设计院，重庆 400015）［摘要］重庆西永综保区监管大楼办公主楼为大跨度连体结构，连接体跨度为58.6m，连接体底部与顶部均采用钢结构桁架与两侧的筒体相连形成巨型框架。通过对比分析确定了钢桁架的结构方案，按抗震性能化设计的概念进行结构设计；采用SAP2000软件进行了弹塑性时程分析，分析了连接体桁架及筒体的受力性能；并通过振动台试验和节点试验验证了结构及节点连接的可靠性，并在计算分析及试验结果的基础上采取了相应的抗震加强措施。［关键词］连体结构; 钢桁架; 振动台试验中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2015)01-0021-05Structural design of Regulatory Building in Chongqing Xiyong Integrated Free Trade ZoneSu Weidong, Shu Yunfeng, Lin Feng, Rao Li, Li Yunzhu(Chongqing Architectural Design Institute, Chongqing 400015, China)Abstract: The Regulatory Building in Chongqing Xiyong Integrated Free Trade Zone is a largespan connected structure with the connected body of 58.6m. Steel trusses set in bottom and top of the connected body connect with the tubes at two sides to form a mega frame. The structure scheme of steel trusses was determined through comparative analyses, and the structure was designed according to the concept of performance-based seismic design. The software SAP2000 was used to carry out the elasto-plastic time-history analysis and analysis on the mechanical properties of the steel trusses and tube structure. By shaking table tests and joint tests, the reliability of the structure and joint connections were verified. Relevant seismic strengthening measures were taken based on the calculation analyses and experimental results.Keywords: connected structure; steel truss; shaking table test作者简介：苏卫东，学士，院副总工程师，教授级高级工程师，一级注册结构工程师，Email：812282209@qq.com。参考文献［1］JGJ 3—2002 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, 2002.［2］GB 50011—2010 建筑抗震设计规范［S］.北京:中国建筑工业出版社, 2010.［3］舒云峰,苏卫东,林锋，等. 重庆西永综保区监管大楼弹塑性时程分析［J］.建筑结构,2012,42(S2):107-111.［4］李英民,韩军,郑妮娜,等.重庆市西永综保区监管大楼振动台试验报告［R］.重庆：重庆大学,2010.［5］李英民,韩军,齐太阳,等.重庆西永综保区监管大楼钢桁架节点受力性能试验研究［R］.重庆：重庆大学,2012.
