摘　　要：设计了4个两种不同边缘约束措施的叠合板式剪力墙和2个普通剪力墙模型,进行了在低周反复荷载下的对比试验研究,分析了结构的破坏形态、变形能力、承载力、延性、滞回特性等。同时运用有限元方法对剪力墙试件进行了模拟计算,研究了在低周反复荷载作用下,不同轴压比对叠合板式剪力墙的破坏形态和变形性能的影响。Four superimposed slab shear walls with edge restricted measures of two different forms and two general shear walls were designed.Comparative experimental studies on superimposed slab shear walls and two general shear walls under low cyclic loading were conducted.Such as the structural failure mode,deformation capacity,bearing capacity,ductility,hysteresis property were analyzed systematically.Through finite-element method,the superimposed slab shear walls and two general shear walls were analyzed.The failure mode and the seismic behavior of the superimposed slab shear walls under cyclic loads,especially under different axial loads,are closely examined.
