摘　　要：选取剪力墙结构体系中较为薄弱的抗震构件“一”形剪力墙,进行了 3个 1 /3缩尺的带钢筋、钢骨暗支撑剪力墙以及普通RC剪力墙构件的低周反复荷载试验,比较分析了它们的承载力、刚度、延性、滞回特性、耗能能力及破坏机制,并提出抗震设计建议。In this paper, firstly, -shaped shear wall is selected to research, which is relatively weak part in shear wall structural system. Secondly, based upon the experimental study on the seismic behavior of three 1/3 scale shear walls with concealed steel bracings or concealed SRC bracings, the effects of concealed bracings on the bearing capacity, stiffness and its attenuation, ductility, hysteresis property, energy dissipation and failure phenomena of these three shear walls are discussed. Thirdly, some seismic advice on design of the shear walls is provided.
