【摘要】 对 DS型多孔砖砌体墙片进行了低周反复水平荷载作用下的试验 ,分析了墙片的破坏特征 ,得到了墙片的骨架曲线、延性系数、变形能力及刚度衰减规律等 ,提出了墙片抗剪承载力及变形计算公式 .根据墙片的等效弹性反应分析了墙片的抗倒塌能力 ,表明带构造柱圈梁墙片具有足够的抗倒塌能力 .更多还原

【Abstract】 Experiments with DS type porous masonry walls are carried out with low cyclic repeated horizontal loading. Failure characteristic is investigated. Skeleton curve, ductility coefficient, deformability and stiffness degrading of walls are obtained. Formulation of shear bearing capacity and deformation are proposed. Based on the equivalent elastic response it is shown that porous masonry walls with reinforced concrete tie beam have enough collapse resistant capacity.更多还原
