摘要：

摘要：为研究预制钢筋混凝土框架结构内嵌竖缝剪力墙体系(PRCFW)的抗震性能，设计了2个单跨双层、缩尺比为1∶2的PRCFW试件，并进行了拟静力试验研究.通过分析试件的破坏机制、刚度退化、变形和延性以及滞回耗能性能等，综合考察该结构体系的破坏模式和变形能力.试验表明：现浇节点未发生明显破坏，满足强节点弱构件要求；试件具有良好的延性，平均位移延性系数均大于3；竖缝墙由缝间墙受弯破坏最终发展成贯通各墙肢竖缝根部的剪切破坏；竖缝剪力墙与预制框架间螺栓连接板及其抗剪连接件未发生破坏.试验能够为该体系的进一步研究和工程应用提供参考.

Abstract:

Abstract： In order to study the seismic performance of prefabricated reinforced concrete frame with infill slit shear walls (PRCFW), two half-scale PRCFW models with one bay, two stories were designed to conduct low cyclic load. The failure mechanism and deformation capacity of PRCFW were gained after the analysis of the failure mode, stiffness degradation, ductile behavior and performance of energy dissipation of specimens. Experimental studies show that the castin-situ joint presents good working performance during this experiment, and the seismic design requirement of strong connection-weak bar is satisfied. The PRCFW has good ductility with a ductility factor greater than 3. The failure mode of slit shear walls is changed and developed from the bending failure of shear wall into the shear failure whose shear crack runs through the whole shear wall. Besides, no failure occurs in the connection between the frame and the infill wall. Moreover, the shear connector worked well. The test results can provide useful information for further research and engineering application of PRCFW.
