EXPERIMENTAL STUDY ON BRICK WALLS STRENGTHENED WITH SIDED LATTICED STEEL PLATE
-
摘要: 通过对高宽比为0.7和1.75的4片墙体进行拟静力试验,研究单面格构式钢板加固砖砌体墙后,墙体的破坏特征以及承载力、变形性能等抗震性能的改善情况。其中2片为对比墙,另2片为单面格构式钢板加固墙体。试验结果表明:单面格构式钢板加固砖墙后,高宽比为0.7的墙体承载力提高约50%,高宽比为1.75的墙体承载力基本没有提高,加固后墙体的变形性能得到了较大的提高。Abstract: Pseudo-static test of four walls with aspect ratio of 0.7 and 1.75 was carried out to study the improvement of seismic performance of sided latticed steel plate reinforced brick masonry wall,the wall failure characteristics and bearing capacity and deformation properties.Of which 2 walls were the reference ones,and the other two were sided lattice steel plate reinforced walls.The experimental results showed that the bearing capacity of side latticed steel plate reinforced brick wall of 0.7 aspect ratio increased by about 50%,basically no increase in wall bearing capacity of 1.75 aspect ratio,the deformation properties of reinforced wall were greatly improved.
