摘要:
通过对非加劲、十字加劲、开洞和开洞开缝四组钢板剪力墙试件进行低周反复荷载试验, 系统研究了
这四种形式钢板剪力墙的整体抗震性能, 对比分析其滞回曲线、承载能力、抗侧移刚度和延性等性能指标.试
验结果表明:非加劲钢板剪力墙具有较高的抗侧移刚度和承载能力, 而其滞回曲线却呈现出明显的捏缩效应;
非加劲钢板墙设置了十字加劲肋后, 其滞回曲线的捏缩效应基本没有改变, 而内填钢板的抗侧移刚度和承载
能力可大幅度提高;非加劲钢板墙开设了洞口或缝之后, 内填钢板的抗侧移刚度和承载能力虽有所下降, 但是
其滞回曲线很饱满, 改善了非加劲薄钢板墙在循环荷载作用时零位移附近的零刚度、甚至负刚度现象, 显著地
提高了其耗能能力.
