摘　　要：为研究空心砖体系的抗震性能,对3种砌筑形式的6片页岩空心砖墙体进行了低周反复荷载试验。阐述了试件的破坏过程,探讨了墙体的破坏特征、承载能力、滞回性能、刚度退化、延性、能量耗散等问题。研究结果表明:配置水平钢筋不仅可以提高墙体的承载能力,而且可以大大提高墙体的抗震能力和变形性能。水平钢筋对墙体可起到有效的约束作用,使破坏的墙体不倒塌,在实际工程中设置水平钢筋是非常必要的。In order to investigate the seismic behavior of cavity brick masonry structure, the low cyclic reversed lateral loading tests on six pieces of shale cavity brick masonry wails which used three bricklaying patterns have been carried out. The failure proceeding of the specimens are represented, and the failure modes, bearing capacity, hysteretic characteristics, skeletoln curves, ductility and energy dissipation are investigated. The result of investigation shows that the steel reinforcement not only can improve the bearing capacity of the masonry walls, but also can greatly inforce the seismic behavior and the deformation behavior of the wall. The steel reinforcement can restrict the wall effectively and make the broken wall not collapse. Putting steel reinforcement in the masonry wall is very essential in the real structure.
