摘　　要：文章为考察外套预制加固法中螺栓连接节点的抗震性能设计了4组拟静力试验,分别考察预埋螺栓连接的预制剪力墙片抗弯、抗剪性能,得出了试验体的强度、刚度、延性和耗能性能参数。试验结果表明:墙片的滞回曲线比较饱满,承载力接近极限时出现捏拢现象。螺栓连接件能够充分传递竖向应力和剪力,将预制剪力墙片连接成一个整体。型钢边缘构件可以有效地增加构件的延性和耗能能力,各构件承载力突降前位移角至少达到2%。The seismic behavior of four pieces of precast cantilever RC walls with bolted connections is examined by quasi-static tests. The strength, the stiffness, the ductility and the energy dissipation capacity of these specimens are evaluated from the experimental results. It is demonstrated that the hysteresis loops of pre-cast walls with bolted connections are fat and pinching was observed when the maximum bearing capacity is approached. The bolted con- nection is deemed sufficient to transfer both vertical and horizontal forces between wall pieces. The embedded steel boundary element offers the wall pieces good ductility and energy dissipation capacity. All specimens reach at least 2% drift before significant strength degradation occurrs.
