摘　　要：该文对4个两边连接钢板组合剪力墙在滞回荷载作用下的性能进行了试验研究。研究了混凝土板与角钢端部的间距以及端部设置加劲肋对两边连接钢板组合剪力墙力学性能的影响。试验结果表明:在钢板角部设置短加劲肋能有效提高构件的延性和耗能能力,相比不设置加劲肋试件,最大层间侧移角由1/35提高到1/25,能量耗散系数提高了35%。混凝土板和角钢的间距也影响构件的受力性能,设置的过大或过小都会使试件节点过早出现破坏。A total of 4 composite steel plate shear walls connected with frame beams under cyclic load were tested in present research. The influence of unrestrained strips （between concrete panel and steel angle） and stiffeners at the comer of steel plate was studied. The experimental results illustrated that welding stiffeners to the comer is an effective way to avoid the early failure of specimen and to improve the energy dissipation ability. Comparing to the specimens without stiffeners, the maximum storey drift ratio of specimen with stiffeners improved from 1/35 to 1/25, and the energy dissipation ratio increased by 35%. The reasonable unrestrained strip height is another important parameter in the design of composite steel plate shear wall.
