【摘要】 为满足低烈度区多层装配式混凝土(PC)墙板结构的抗震性能需求并实现快速装配，提出一种水平键槽式接缝连接形式，通过对6片采用该连接的PC墙板试件开展低周反复荷载试验，探究接缝处有、无竖向灌浆套筒连接、轴压比及墙厚等因素对墙板抗震性能的影响．试验结果表明：施加轴压力或增添灌浆套筒连接对试件的耗能、承载能力及延性均有明显提高，但轴压比的继续增大使得耗能能力和延性有所降低；减小墙厚对试件耗能及承载能力影响显著．采用ABAQUS对低周反复荷载下的墙板试件开展了有限元分析，在验证了模型的准确性后，对比探讨了套筒位置及套筒连接钢筋直径对墙板承载能力的影响，并给出了水平键槽接缝连接的PC墙板的承载力简化计算方法，计算结果与试验结果误差在15%以内．更多还原

【Abstract】 In order to meet the seismic performance and rapid assembly requirements for multi-layer precast concrete(PC) wall structures among low seismic intensity areas,a type of horizontal keyway joint connection was proposed.The low cycle loading test was carried out on 6 PC wall specimens connected by the joint to investigate the impact of the addition of vertical grouted sleeves,axial compression ratios,and wall thickness on the seismic performance of specimens. Results indicate that the energy dissipation capacity,bearing capacity and ductility of specimens are enhanced obviously when applying axial compression or adding grouted sleeves. However,the energy dissipation capacity and ductility of specimens decrease as the axial compression ratio continue to increase.The reduction in wall thickness has remarkable effects on the energy dissipation and bearing capacity of specimens.The finite element analysis of PC wall specimens under low cycle loading were conducted by using the ABAQUS. Based on the accuracy of the proposed models,the comparative analysis was carried out to investigate the layout position and diameter of connecting reinforcement of grouted sleeves on bearing capacity of walls. The simplified calculation method of bearing capacity was subsequently put forward,and the error between the calculation and experimental results is within 15%.更多还原
