摘　　要：本文选取短肢剪力墙结构体系中较为薄弱的抗震构件“一”形短肢剪力墙,采用不同的暗支撑型式进行了两个1/2缩尺的带暗支撑短肢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,建立了其承载力计算模型与方法。计算结果与实测值符合较好。In this paper, firstly, ―-shaped short pier shear wall is selected to research, which is unsubstantial part in short pier shear wall structural system. Secondly, based upon the experimental study on the seismic behavior of two 1/2 scale short pier walls with different forms of concealed bracings, the effects of concealed bracings on the bearing capacity, stiffness and its attenuation, ductility, hysteresis property, energy dissipation and failure phenomena of these two short pier shear walls are discussed. Thirdly, the mechanical models and the formulas of bearing capacity are established, and the results from the formulas and those from experiment are in good agreement.
