(同济大学建筑设计研究院,上海 200092)[摘要]上海国际设计中心为一呈h形不等高双塔连体结构,采用钢框架核心筒结构体系。详细介绍了该结构分析与设计的有关内容,包括主、副塔楼结构抗侧力体系、连体结构体系选型与概念设计、相关的特殊构造措施;并对多遇地震下主副塔结构响应的对比分析、连体结构中震分析、副塔倾覆效应分析、结构的弹塑性时程分析进行了重点介绍。分析结果表明,大震作用下,在其他构件进入塑性的情况下,连体部位依然保持弹性。[关键词]连体结构;框架核心筒结构;中震弹性分析;弹塑性时程分析Design of Asymmetry Double-Tower Connected Structure of Shanghai InternationalDesign CenterHe Zhijun,Ding Jiemin,Wu Honglei (Architectural Design and Research Institute of Tongji University,Shanghai 200092,China)Abstract:Shanghai international design center is a h-shape asymmetry double-tower connected structure,which is designed as steel frame-core wall structure. The structural analysis and design are presented,including structural system selection and concept design of lateral resistant system of the dual towers,connected structures and some special seismic fortification measures. The contrast analysis of the single tower structure and dual towers connected structure under frequently occurred earthquake action,moderate earthquake elastic analysis of the connected structure,elasto-plastic dynamic time history analysis of the whole structure under seldom occurred earthquake and overturning action of the minor tower are introduced. Analysis results show that the connected structures remains elastic under the action of seldom occurred earthquake while the other members have turned into inelastic.Keywords:connected structure; frame-core wall structure; elastic/elasto-plastic analysis; moderate earthquake; dynamic time history; analysis作者简介:何志军(1972-),博士,高级工程师,从事大型复杂结构设计研究。参考文献[1]高层建筑混凝土结构技术规程(JGJ3—2002)[S].[2]徐培福,傅学怡,王翠坤,等. 复杂高层建筑结构设计[M]. 北京:中国建筑工业出版社,2005.[3]徐培福,等.关于超限高层建筑抗震设防审查的若干讨论[J].土木工程学报,2004,37(1).[4]卞朝东,李爱群,娄宇.高层连体结构振型及其参与系数的分析[J].建筑科学,2002,18(44).[5]张春浓,徐斌.凯晨广场多塔连体结构设计研究[J].建筑结构,2008,38(1).
