上海国际设计中心不对称双塔连体结构设计研究

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。

Design of Asymmetry Double-Tower Connected Structure of Shanghai International Design Center

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.
