钢板砌体组合短肢剪力墙加固实验研究

为了研究钢板加固砌体短肢剪力墙体的受剪破坏特征,以及承载力、变形等抗震性能的改善情况,本文分别进行了一片未加固的和一片单面钢板加固的砌体短肢剪力墙低周往复水平加载拟静力对比实验。实验结果表明,相对于未加固的情况,单面加固的钢板砌体短肢组合剪力墙承载力没有提高,但变形性能得到大幅改善,耗能能力有了较大的提高。

EXPERIMENTAL STUDY ON SINGLE-SIDED STEEL PLATE REINFORCED MASONRY COMPOSITE SHEAR WALL

In order to observe the seismic performances such as the bearing capacity and deformation of single-sided steel plate reinforced short-leg masonry shear wall,one unreinforced and one single-sided steel plate reinforced short-leg masonry shear wall pseudo-static tests were studied.The experimental results show that,comparing with the unreinforced one,the bearing capacity of single-sided steel plate reinforced short-leg masonry shear wall has no obvious improvement,but the deformation properties as well as the energy dissipation capacity has been greatly improved.
