摘　　要：通过对三片带钢筋混凝土边框的粉煤灰小型砌块剪力墙以及相同两片的开洞墙在低周反复荷载作用下的试验 ,分析了墙体边框柱和内部砌体的共同工作性能 ,描述了墙体的破坏形态 ,绘制了试件受力的滞回曲线和骨架曲线 ;同时对这种剪力墙的刚度退化、变形能力、延性系数、粘滞阻尼系数等抗震性能指标进行了分析。Through the low frequency cyclic loading tests on two shear walls made of coal ash blocks with reinforced concrete frame and other two similar shear walls with openings, the interacting behavior of the R C frame column and the inner block wall is studed. The failure pattern of the wall is described. The hysteretic curves and skeleton curves of the testing models are drawn. The indices of the seismic performance of the shear wall, such as stiffness degradation, deformation capability, ductility coefficient and viscous damping coefficient are also analyzed.
