摘要
提出一种新型混凝土横孔连锁空心砌块,通过在新型砌块墙体中设置构造柱和水平钢筋混凝土带,形成对墙体的约束。进行了3片新型混凝土横孔连锁空心砌块承重墙体的拟静力试验,得到了其破坏形态、滞回特性、变形能力、刚度退化等情况。试验结果表明:设置构造柱和水平钢筋混凝土带能有效提高墙体的开裂荷载和极限荷载,该新型砌块墙体具有较好的抗震性能。
A new type of hollow block,construction column and horizontal reinforced concrete strips in the walls forming restrained masonry which is named concrete cross bore chain hollow block,was advanced.Based on the test of three cross bore chain hollow block bearing masonry walls under the low cyclic reverse load,the failure modes,hysteresis characteristic,deformability,stiffness degradation and other seismic behaviors were studied.The test results show that the masonry wall with construction column and horizontal reinforced concrete strips can increase cracking resistance and load-bearing capacity,and this new type of masonry wall has good seismic behavior.
