摘　　要：采用连接钢框和高强螺栓作为连接件,可实现相邻上下层预制混凝土墙板之间的干式连接。为评价该全装配式剪力墙的抗震性能,对2个试件分别进行了单调加载试验和低周反复荷载试验。试验结果表明,该新型全装配式剪力墙的变形能力、延性性能及耗能能力略优于或相当于装配整体式剪力墙及现浇剪力墙。在试验研究的基础上,计入连接件的影响,推导了剪力墙屈服点、峰值点、破坏点荷载和侧移的理论公式。该计算公式反映了构件的主要受力特点,与试验结果吻合较好。计算结果表明：连接钢框的变形对总侧移的影响可以忽略不计,高强螺栓的滑移引起的顶点侧移占总侧移的12.0%～44.8%。The connecting steel frame（CSF） and high strength bolt（HSB） are utilized as connecting components to connect the upper and lower precast reinforced concrete shear wall panels. To evaluate the seismic performance of this innovative precast shear wall with horizontal joint, monotonic loading test and low-cyclic reversed loading test were conducted on two test walls. The test results show that the deformability, ductility, and energy-dissipating capacity of the test walls are comparable to those of other assembled monolithic shear wall as well as the cast-in-situ shear wall. Based on the experimental investigation, the theoretical formulas in consideration of the effect of the connecting components for the loads and displacements of the yielding point, peak point, and failure point of the test walls are deduced. These formulas reflect the major features of this novel structural member, the results of which meet well with the test results. The computed results show that the influence of the deformation of connecting steel frame on the total lateral displacement could be ignored, while the lateral displacement caused by the slippage of the high strength bolts takes up 12.0%～44.8% in the total lateral displacement.
