摘要
通过 9片约束页岩砖砌体墙的低周反复水平荷载试验 ,研究了约束页岩砖砌体墙的破坏特征、抗震性能和抗震受剪承载力计算公式 .试验表明约束页岩砖砌体墙具有良好的变形性能和较高的抗震受剪承载力 ,其延性系数接近约束粘土砖砌体墙延性系数 ,其抗震受剪承载力计算式可采用与约束粘土砖砌体墙相同的公式 .在抗震性能上页岩砖完全可以取代粘土砖作为约束砌体墙的砌筑材料 .
The experiments of 9 pieces of confined shale brick masonry walls subjected to low-cyclic reversed horizontal load were carried out, and the failure characteristics, seismic behavior and lateral-resisting bearing capacity of this kind of walls were studied. Through the experiments and analysis, it can be concluded that confined shale brick masonry wall has good deformation property and high lateral-resisting bearing capacity, its ductility is close to confined clay brick masonry wall's, and its lateral-resisting bearing capacity is higher than confined clay brick masonry wall's. In seismic behavior confined shale brick masonry wall can be a good substitute for confined clay brick masonry wall.
