摘　　要：为改善预制挤塑板夹心填充墙与钢筋混凝土框架间的相互作用,开展了缩尺比为1∶2的柔性、半柔性填充摩擦耗能装配式连接填充墙框架和纯框架的低周反复加载试验,分析了预制挤塑板夹心填充墙在新型装配式连接节点下不同填充方式对框架破坏形态、滞回特性、变形等抗震性能的影响。研究结果表明:预制墙-框架间采用半柔性或柔性填充装配式连接与空框架相比,抗震性能有所提升;预制墙-框架间采用半柔性与柔性填充装配式连接相比,在延性、承载力退化方面相差无几,而在框架裂缝开展、刚度、承载力等方面前者表现得更加优越。因此在预制挤塑板夹心填充墙框架间应采用半柔性填充装配式连接构造方式。In order to improve the interaction between prefabricated extruded panel sandwich infill walls and reinforced concrete frames,low circumferential repeated loading tests of flexible and semi-flexible infill friction energy-consuming assembled connection infill wall frames with a scaling ratio of 1∶2 and pure frames were carried out,and the main study analyzed the effects of different infilling methods of the prefabricated extruded panel sandwich infill walls under the new assembled connection nodes on the seismic performance of the frames in terms of damage patterns,hysteresis characteristics,deformation,and other seismic performances.The results show that the seismic performance of prefabricated walls-frames with semi-flexible or flexible infill assembly connection is improved compared with that of empty frames,while the difference between prefabricated walls-frames with semi-flexible and flexible infill assembly connection is not much in terms of ductility and bearing capacity degradation,and the former performs much better in terms of framing crack development,stiffness,and bearing capacity.Therefore,semi-flexible infill assembly connection should be used between the frames of prefabricated extruded panel sandwich infill walls.
