【摘要】 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。更多还原

【Abstract】 Shale hollow bricks can take the place of common bricks to some extent.But the weak seismic behavior of hollow brick masonry walls affects the application of the hollow bricks in the engineering.Partical reinforcement in the wall can improve the seismic performance of walls.In order to investigate the effect of seismic behavior of this structure,the low cyclic reversed lateral loading tests on six pieces of shale hollow brick masonry walls which used three bricklaying patterns have been carried out.The bearing capacity,hysteretic characteristics,ductility and energy dissipation were researched.The result of investigation shows that setting steel reinforcement in the wall not only can improve the bearing capacity of the masonry walls,but also can greatly improve the seismic behavior and the deformation behavior of the wall.更多还原
