Abstract:

在综合考虑加劲肋型、组合型及防屈曲型薄钢板剪力墙优缺点的基础上,提出一种新型的防屈曲加劲肋钢板剪力墙。介绍了该新型防屈曲约束加劲肋钢板剪力墙的构造与工作原理,设计了一个13的缩尺试验试件,对其进行了拟静力试验研究,系统地分析了该新型钢板剪力墙的抗震性能及破坏特征。试验结果表明,所提出的防屈曲约束加劲肋钢板剪力墙具有较高的抗侧刚度、延性及耗能性能;预制混凝土板及加劲肋在一定程度上抑制了钢板的屈曲变形,充分地发挥了钢材的塑性,使其具有良好的滞回耗能性能;角部连接失效是导致试件破坏的主要因素。综上所述,所提出的防屈曲约束加劲肋钢板剪力墙抗震性能良好,是一种较好的新型抗侧力构件。
