    摘要:

    为进一步改善一字型内置竖向型钢混凝土低矮剪力墙的抗震性能，设计和完成了2个剪跨比为1.0的钢板带加强型内置竖向型钢混凝土低矮剪力墙低周往复水平加载试验，并与1个未设置钢板带的内置竖向型钢混凝土低矮剪力墙进行对比分析。试验结果表明：钢板带的设置使剪力墙的水平承载力有显著提升，极限位移角提高20%左右，满足了相关规范极限位移角大于1/100的要求；钢板带的设置使试件破坏模式发生变化，总耗能有大幅度提升；钢板带的设置要适度，不能过强，以免形成新的薄弱区。

    Abstract:

    In order to improve seismic behavior of one-shaped concrete squat shear wall with built in vertical steels in the rectangular section, two concrete squat shear wall specimens were designed and fabricated with an aspect ratio of 1.0, which enhanced by horizontal steel plates other than built-in vertical steels in the sections. Mechanical behaviors of those specimens were tested under reversed cyclic lateral loads and a constant vertical load. The test results were compared with a specimen without enhancement of horizontal steel plates, which indicates that the peak lateral loads of specimens with steel plates are improved significantly. The ultimate drift ratios of specimens with steel plates are improved by 20% and are larger than 1/100, which meets the relevant specifications. Steel plates change the failure modes of specimens, and the total energy dissipation of specimens with steel plates are improved substantially. The enhancement should be kept in a suitable range, otherwise new weak areas will be formed if the horizontal steel plates are too strong.
