摘　　要：介绍了弱连接双塔高层结构分析和设计的有关内容,包括塔楼抗侧力体系、连体结构体系与概念设计、相关特殊构造措施。通过对连体结构的工程实例进行在地震作用下反应谱和弹性时程分析,探讨连体结构的动力反应特征;用EPDA和EPSA分析软件分别进行在罕遇地震作用下的弹塑性时程分析和静力弹塑性分析,对该工程的结构抗震性能进行评估。Structural analysis and design of a twin towers were presented. These two buildings are connected by two weakly connections along the tower height. This paper describes the details of structural system selec-tion and concept design of lateral resistant system of the dual towers. Seismic design of connected structures, including some special measures, was also introduced. Dynamic performances of this twin tower system were investigated through response spectrum analysis and elastic time-history analysis. The elastic-plastic time-his-tory analysis and static elastic-plastic analysis （push-over） were also performed to evaluate seismic behaviors of the connected buildings.
