摘　　要：通过加气混凝土砌块填充墙的平面外静力加载试验,分别考虑高厚比、砌体强度、拉结筋间距等因素对平面外受力填充墙承载力、位移影响,观察其破坏形态、破坏过程,得出填充墙平面外荷载-位移曲线、拉结筋应变曲线,并将试验结果进行对比。结果表明,墙体破坏位置与四边约束的强弱有关,高厚比是影响填充墙平面外承载力的决定性因素,拉结筋可以增强填充墙平面外稳定性。Through the out-of-plane static loading experiment of aerated concrete masonry, the height-thickness ratio, strength of masonry, strength of four boundary constraints, spacing of tie bars are considered in the experiment to analysis the influence to bearing strength and displacement of the out-of-plane. The failure pattern and failure process with the out-of-plane loading are studied, the load-displacement curves of the wall and load-strain curves of tie bars are derived, and the outcomes of the experiment are compared. The results indicate that the destroy position is concerned with the strength of four boundary constraints and the height-thickness ratio is the decisive factor and tie bars can enhance the out-of-plane stability of infill walls.
