摘　　要：为研究新型装配式自复位筒体结构的整体抗震性能,并检验该结构特殊细部构造的有效性,同济大学土木工程防灾国家重点实验室开展了高层钢框架-自复位混凝土筒体组合结构的模拟地震振动台试验。试验对象为某一10层装配式结构,结构体系由外围承重框架和承担水平作用的自复位混凝土筒体组成。墙柱间滑槽式连接节点以及全铰接的框架连接方式用于完全分离结构的承重体系和抗侧体系,以实现结构主体在地震作用下的低损伤特性。对该振动台试验模型设计进行了介绍,详细说明了结构体系的作用机理、试验模型的设计计算流程和特殊的细部构造,为今后类似的装配式高层自复位筒体结构的设计与试验提供参考。To study the overall seismic performance of the brand-new prefabricated self-centering tube structure and verify the effectiveness of the special details,the shaking table test of a high-rise steel frame-self­centering RC tube composite structure was carried out in the State Key Laboratory for Disaster Reduction in Civil Engineering,Tongji University.The test object was a ten-story prefabricated structure which was composed of the gravity frame on the periphery and one self-centering RC tube utilized to resist horizontal actions.The channel jointed between tube walls and columns,as well as the hinge connections of the frame,were used to separate the gravity-bearing system and the lateral force-resisting system completely,so as to ensure the low-damage characteristics of the main part of the structure under seismic excitation.In this paper,the model design of the shaking table test was introduced,and the mechanism of the structural system,the design and calculation process of the model building and the special details were described in detail,which provided reference for the design and test of prefabricated high-rise self-centering tube structures with similarity in the future.
