［摘要］為研究空心磚體系的抗震性能,對3種砌筑形式的6片頁巖空心磚墻體進(jìn)行了低周反復(fù)荷載試驗。闡述了試件的破壞過程，探討了墻體的破壞特征、承載能力、滯回性能、剛度退化、延性、能量耗散等問題。研究結(jié)果表明：配置水平鋼筋不僅可以提高墻體的承載能力，而且可以大大提高墻體的抗震能力和變形性能。水平鋼筋對墻體可起到有效的約束作用,使破壞的墻體不倒塌，在實際工程中設(shè)置水平鋼筋是非常必要的。

Abstract: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 walls 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,skeletolncurves,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.
Keywords:reinforced shale cavity brick; seismic behavior; failure mode; energy dissipation
