摘　　要：进行了3个1/3缩尺的低剪力墙的抗震性能试验研究,包括1个普通混凝土低剪力墙、1个内藏钢框架混凝土组合低剪力墙和1个内藏钢桁架混凝土组合低剪力墙。在试验研究基础上,对比分析了各剪力墙的刚度及其衰减过程、承载力、延性、滞回特性、钢筋应变、耗能能力及破坏特征。试验表明:内藏钢框架和内藏钢桁架混凝土组合低剪力墙的抗震性能比普通混凝土低剪力墙明显提高。The experimental studies on the seismic behavior of three 1/3 scale low - rise shear walls, including a low-rise shear wall with concealed steel frame, a low-rise shear wall with concealed steel truss and a usual one, has been conducted. Based upon the experimental studies, the stiffness and its attenuation, bearing capacity, ductility, hysteresis property, steel bar strain, energy dissipation and failure phenomena of the shear walls are analyzed and contrasted each other. The experimental results show that the seismic behavior of the low-rise shear walls with concealed steel frame has been obviously improved and the seismic behavior of the low-rise shear walls with concealed steel truss has been significantly increased in comparison with the usual one_
