摘　　要：为研究复合剪力墙板的抗震性能,采用荷载-变形双控制水平加载方式进行7组共15片墙板试件在低周反复荷载作用下的试验,分析各试件的滞回特性、耗能性能、延性等.试验结果表明,各试件的滞回曲线较为饱满;施加一定轴压后试件的耗能能力和延性会更好;墙板为两侧等厚混凝土层组合、有边框、现浇时,其抗震性能优于不等厚混凝土层组合、无边框、普通销键连接的装配整体式复合剪力墙板.In order to study the anti-seistnic performance of composite shear wall slab, 7 groups of composite shear wall slab samples of 15 pieces were tested under cyclic horizontal loading by using load-deformation double control. Their hysteretic loops, energy performance, and ductility were analyzed. The test result showed that the hysteresis loops of the samples were comparatively full. The energy dissipation ability of the samples subject to fixed-axis compression and their ductility would be better. Cast-in-place composite shear walls with isopachous concrete borders and peripheral frames had better anti-seismic performanee than those with non-isopachous concrete borders and without frames and general pin key assembly.
