摘　　要：目的研究水平配筋煤矸石多孔砖墙片抗震性能,为煤矸石多孔砖这种新型墙体材料在地震区的推广应用提供试验和理论依据.方法通过水平配筋墙片与素墙片在低周反复水平荷载作用下的试验,分析墙片的破坏形态,得到了墙片的滞回曲线、骨架曲线、刚度衰减规律及水平钢筋在试验过程中的应变情况.结果墙片破坏主要为剪切破坏;水平配筋墙片滞回曲线有两次峰值,墙片开裂前,水平钢筋应变很小,开裂后,应变迅速增大.水平配筋墙片的极限承载力为素墙片的1.3倍.结论水平配筋多孔砖墙片具有较高承载力和抗震性能,抗倒塌能力强.In this paper,research on the seismic performance of horizontally reinforced gangue porous brick masonry is conducted to provide theoretical basis design in the earthquake region.Through the horizontal low cyclic load test of horizontally reinforced gangue porous brick masonry and analysis of the damage form of wall,the hysteresis curve,skeleton curves,stiffness decay laws and the strain of horizontal reinforcing steel bar in the test are obtained.The destroy of the wall major for shear failure;reinforcement wall hysteresis curve has two peak,before cracking of the wall,the strain of level reinforced is very small.After cracking,strain increases quickly,ultimate bearing capacity of level of reinforcement of wall for element wall piece of 1.3 times.The reinforcement porous brick wall with high bearing capacity and seismic performance,strong ability of collapsed.
