【摘要】 通过3片墙体的抗压试验和10片墙体的水平低周反复荷载试验,研究了低强度空斗墙的抗压和抗震性能。在水平低周反复荷载试验中,比较了不同砂浆强度和砌筑方式的空斗墙的破坏形态、承载能力、变形能力、滞回特性、耗能能力等。试验结果表明,不同砌筑方式空斗墙的抗压承载力差异不大;低强度空斗墙抗震试验结果的随机性和离散性很大;低强度空斗墙的抗震性能明显差于相同条件的实心墙;砂浆强度和砌筑方式对空斗墙的抗震性能均有一定影响。采用已有的经验公式对空斗墙的抗压和抗剪承载力进行了计算,计算与试验结果基本吻合。更多还原

【Abstract】 Three walls under compression and 10 walls under low frequency cyclic horizontal load were tested to study the compressive and earthquake resistant behavior of low strength cavity walls.By the low frequency cyclic horizontal load tests,the failure mode,ultimate strength,hysteresis loops,and energy dissipation of walls with different mortar strength and construction modes were analyzed.The experimental results showed that the difference between the compressive load capacities of the cavity wall and the solid wall was insignificant.The earthquake resistant behaviors of low strength cavity walls were random,but obviously weaker than that of solid wall.The mortar strength and construction modes had effect on the seismic behavior of low strength cavity walls.The compressive and shear load capacities of the cavity walls were calculated using the experiential formulas,and were similar with the experimental results.更多还原
