摘　　要：对3层装配式环筋扣合锚接混凝土剪力墙进行足尺拟动力试验,破坏现象为暗梁处裂缝开始沿后浇带水平方向发展,最后发展为斜角45°的裂缝,墙体的多数裂缝也朝水平方向发展,最终发展为斜裂缝,结构的位移也较小,表明该新型结构在7度和8度多遇地震作用下,结构没有发生损坏。层间位移角最大时达到1/1 127,结构受力仍处于弹性范围内,满足"小震不坏"的设防目标;在7度罕遇地震作用下,仍没有明显的裂缝产生,满足"大震不倒"的设防目标。In order to study the aseismic behavior of precast shear walls with annular closed reinforcement, a threestory full-scale model was built in laboratory for an elastic pseudo-dynamic test. The cracks started from internal beam and developed along the post-pouring belt in the horizontal direction. Finally, the cracks developed into a 45 ° angle cracks, most of the cracks developed in the horizontal direction, and eventually developed into inclined cracks. The small displacement indicated the new structure did not damage under the action of frequent earthquake. The maximum storey drift angle achieved to 1/1 127.The structure was still in the elastic state, which met the fortification requirements of ＂no damage under the action of frequent earthquake＂. At the 7 seismic precaution intensity under rare earthquake action, no obvious cracks appeared still. The results showed that the shear wall met the requirements of ＂no collaspe under the action of rare earthquake＂.
