摘　　要：提出一种装配式轻钢轻混凝土剪力墙与混凝土楼板的装配连接方式,为研究该连接节点的抗剪性能,开展了4个墙体-楼板连接试件的低周往复加载试验,分析了连接节点的滞回性能、刚度退化、延性、耗能能力及承载力性能。结果表明:不同连接构造形式对墙体-楼板连接节点的承载力影响显著,抗剪螺栓能有效提高节点的刚度与水平抗剪承载力;承载力分析结果显示,设有抗剪螺栓的连接节点承载力比预制墙体抗剪承载力高了34.3%,满足节点承载力要求,最后给出了装配式轻钢轻混凝土墙-楼板连接节点设计建议。This paper proposes an assembly connection method between prefabricated lightweight steel and lightweight concrete shear walls and concrete floors.In order to study the shear performance of the connection joint,low cycle reversed loading tests were conducted on four wall-floor connection specimens.The hysteresis performance,stiffness degradation,ductility,energy dissipation,and bearing capacity performance of the connection joints were analyzed.The results show that different connection structures have a significant impact on the bearing capacity of the wallfloor connection joints,and shear bolts can effectively improve the stiffness and horizontal shear bearing capacity of the joint;the bearing capacity analysis shows that the bearing capacity of connection joints with shear bolts is 34.3%higher than that of prefabricated walls,meeting the requirements for joint bearing capacity.Finally,design recommendations for prefabricated lightweight steel and lightweight concrete wall-floor connection joints are provided.
