摘　　要：通过6个1∶2缩尺的T形截面带暗支撑短肢剪力墙模型的低周反复荷载试验研究,分析比较了带暗支撑T形截面短肢剪力墙和普通T形截面短肢剪力墙的承载力、刚度及其衰减过程、延性、耗能、滞回特性及破坏特征。试验表明,加设钢筋混凝土暗支撑可显著提高T形截面短肢剪力墙的抗震性能。In this paper, based upon the experimental study on the seismic performance of three 1∶2 scale T-shaped short pier walls with concealed bracings and three 1∶2 scale general short pier shear wall, seismic performance of the T-shaped short pier shear walls with concealed bracings, which includes bearing capacity , stiffness and its attenuation, ductility, energy dissipation, hysteresis property and failure mechanism, is compared with that of the general T-shaped short pier shear wall. It shows that the concealed bracings are able to improve greatly the seismic performance of the T-shaped short pier shear wall.
