(重庆市设计院,重庆 400015)[摘要]通过对重庆国际大厦超高层结构方案、结构设计的介绍,论述了采用钢筋混凝土筒中筒结构体系,框架柱选用核心钢管混凝土柱,利用避难层设置钢筋混凝土局部腰桁架等措施。通过多种软件的计算分析比较证明,结构设计安全、合理,满足了工程的抗震性能目标要求。[关键词]筒中筒结构体系;核心钢管混凝土柱;钢筋混凝土局部腰桁架中图分类号:TU318文献标识码:A文章编号:1002-848X(2011)04-0069-05Structural design of Chongqing International BuildingTang Lanyun, Tang Qiming, Wu Shengda(Chongqing Architectural Design Institute, Chongqing 400015, China)Abstract:The structural plan and design of Chongqing International Building were introduced. The project selects reinforced concrete tube in tube structural system, the frame column is steel tube confined concrete column and it uses the partial reinforced concrete frame-wall outriggers. Through-calculation and analysis, the structural design is verified to be safe and reasonable, and the results indicate that the structural design can satisfy the seismic performance requirements.Keywords:reinforced concrete tube in tube structural system;steel tube confined concrete column;partial reinforced concrete frame-wall outriggers作者简介:唐兰云,高级工程师,一级注册结构工程师,Email:cloud881@sina.com。参考文献[1]JGJ94—2008建筑桩基技术规范 [S]. 北京:中国建筑工业出版社,2008.[2]GB50011—2001建筑抗震设计规范[S]. 2008年版.北京:中国建筑工业出版社,2008.[3]刘大海,杨翠如.高楼结构方案优选[M]. 西安:陕西科学技术出版社,1992.[4]JGJ3—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.[5]赵西安.高层结构设计[M]. 北京:中国建筑工业出版社,1995.[6]徐培福.复杂高层建筑结构设计[M]. 北京:中国建筑工业出版社,2005.
