作为非承重结构材料,页岩空心砖能够较好地替代黏土砖。但空心砖墙体抗震性能较差,严重影响其在工程中的应用。局部配筋是提高砌体结构抗震性能的主要方法之一。为研究局部配筋对页岩空心砖墙体抗震性能的影响,对3种砌筑形式6组墙体进行了低周反复荷载试验。研究了局部配筋对该结构承载力、滞回性能、延性和耗能能力等方面的影响。研究结果表明:局部配筋不仅可以提高墙体承载力,而且可以显著提高墙体抗震性能和变形性能。
As a non-load-bearing structural material, shale hollow brick can better replace clay brick. However, the seismic performance of hollow brick wall is poor, which seriously affects its application in engineering. Local reinforcement is one of the main methods to improve the seismic performance of masonry structures. In order to study the effect of local reinforcement on the seismic performance of shale hollow brick wall, three kinds of masonry forms of six groups of walls were subjected to low cycle repeated loading test. The effect of local reinforcement on the bearing capacity, hysteretic behavior, ductility and energy dissipation capacity of the structure was studied. The results show that the local reinforcement can not only improve the bearing capacity of the wall, but also significantly improve the seismic performance and deformation performance of the wall.
