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 study the seismic performance of hollow brick system, three kinds of masonry forms of 6 shale hollow brick walls were subjected to low cycle repeated loading test. The failure process of the specimen is expounded, and the failure characteristics, bearing capacity, hysteretic behavior, stiffness degradation, ductility and energy dissipation of the wall are discussed. The results show that: the configuration of horizontal reinforcement can not only improve the bearing capacity of the wall, but also greatly improve the seismic capacity and deformation performance of the wall. Horizontal reinforcement can play an effective restraint on the wall, so that the destruction of the wall does not collapse, in the actual project to set the level of steel is very necessary.
