预制轻钢轻混凝土剪力墙-楼板连接部抗剪性能试验研究
Experiment on Shear Performance of Prefabricated Lightweight Steel and Lightweight Concrete Shear Wall-Floor Connection
摘要
Abstract
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 wall-floor 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.关键词
