摘　　要：分别对3片拉力螺栓连接墙板和3片剪力螺栓连接墙板进行低周反复荷载试验,对比研究2种螺栓连接的装配式墙板抗震性能;分析各螺栓连接墙板位移组成及其对总变形的贡献,并探讨墙板水平缝传力机理及节点潜在破坏形态。研究结果表明:采用2种不同螺栓连接的墙板均满足低层建筑安全性,但在传力模式、破坏形态、承载能力、刚度及耗能等方面存在差异。螺栓连接墙板水平缝张开是导致墙板刚度减小的主要因素。基于节点破坏形态计算的水平缝抗弯承载力与试验结果吻合较好。To study the seismic performance of precast wall with two different bolted connections,quasi-static tests were carried out on three tension bolted specimens and three shear bolted specimens.The displacement composition of the bolted wall panel and its contribution to total deformation were analyzed.The force transfer mechanism and potential failure patterns of joint were also discussed.The results show that both two types of specimens meet the safety of low-rise buildings,although there are differences in the force transfer mechanism,failure mode,bearing capacity,stiffness and energy consumption.The joint opening mainly leads to the stiffness degradation.Based on the failure pattern of joints,the calculated bending capacities of horizontal joint are in good agreement with the experimental results.
