Experimental Study on the Seismic Behavior of Concrete Perforated Brick with Industrial Wasted Materials Masonry Walls

目的研究工业废渣混凝土多孔砖墙片抗震性能和破坏形式.方法通过3片工业废渣混凝土多孔砖墙片在低周往复水平荷载作用下试验,分析了墙片的破坏特征,得到墙片的滞回曲线、骨架曲线、延性系数.结果与其他多孔砖墙片实验研究进行比较表明破坏形态相似,变形能力较好,抗震承载力较高.结论工业废渣混凝土多孔砖墙片延性比为2.93~3.00,抗震性能较好,抗震抗剪承载力验算可按《砌体结构设计规范》（GB5003-2001）规定执行.

The paper focuses on the seismic behavior as well as failure pattern of concrete perforated bricks with industrial wasted materials masonry walls. Three pieces of concrete perforated bricks industrial wasted materials masonry walls were tested with low cyclic repeated horizontal loading. Failure characteristics were investigated;hysteretic curve, selection curve, and ductility coefficient of walls were obtained. The results show that the failure pattern of concrete perforated bricks with industrial wasted materials masonry walls is similar to those of other experimental study on perforated brick masonry wall, but its deformability is better and its shear bearing capacity is higher. The ductility of concrete perforated bricks with industrial wasted materials masonry walls is 2.93 - 3.00, with better seismic behavior. The shear bearing capacity satisfies the formulation in code for design of masonry structures.
