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。
Through quasi-static tests on four walls with aspect ratios of 0.7 and 1.75, the failure characteristics of the walls and the improvement of the seismic performance such as bearing capacity and deformation performance are studied after the masonry walls with single-section lattice steel plate are reinforced Happening. Two of them are contrasting walls, and the other two are single-pane latticed steel reinforced walls. The test results show that the bearing capacity of the wall with the aspect ratio of 0.7 increases by about 50% and the bearing capacity of the wall with the aspect ratio of 1.75 has not increased after the single-section lattice steel reinforced brick wall. The deformation of the reinforced wall Performance has been greatly improved.
