摘　　要：为研究在水平拼缝位置采用螺栓连接的装配式剪力墙的抗震性能,完成了两个剪跨比为2.2的剪力墙试件的拟静力试验。研究结果表明:两个试件都发生了弯曲破坏,水平拼缝的抗剪承载力满足要求;两试件的破坏均发生在剪力墙水平拼缝截面附近和拼缝下方的下段墙板上,上段墙板本身基本保持弹性;由于连接盒底板连接构造不同,试件S-1发生了高强螺杆拉断的脆性破坏,试件S-2则发生了由较薄螺栓连接垫板的抗弯强度控制的塑性破坏;试件S-2具有较好的自复位能力,延性系数介于3.03~3.7之间,极限位移角满足GB 50011—2010《建筑结构抗震设计规范》限值要求。同时,基于通用有限元软件ABAQUS建立数值模型对试件进行单向推覆分析,分析模型可以较好模拟试件的骨架曲线和破坏模式。To study the seismic performance of the precast shear wall with bolt connections at the horizontal joint, a quasi-static test of two shear wall specimens with a shear-span ratio of 2.2 was conducted. The test results showed that: both specimens suffered bending damage, and the shear capacity of the horizontal joint met the requirements;the damage of both specimens occurred near the horizontal joint and the lower section of the wall panel below the joint, while the upper wall panel basically remained elastic;due to the different forms of the bottom plate of the connection box, brittle damage occurred in specimen S-1 while plastic damage occurred in specimen S-2;the ductility coefficient of specimen S-2 was between 3.03 and 3.7, and the drift value could meet the requirements of Chinese Code for Seismic Design of Buildings(GB 50011—2010). Based on the experimental study, the unidirectional push over analysis based on FE software ABAQUS was conducted the analysis. The proposed FE model could well reproduce the skeleton curve and the failure mode of the specimens.
