| 摘 要： | 实验测定加气混凝土砌块的力学性能和加气混凝土砌体的轴心抗压，抗弯强度和沿通缝截面的抗剪强度，讨论加气混凝土砌体在不同荷载条件下的裂缝发展特点和破坏特征，分析其荷载一住移曲线的发展规律．研究表明：轴心受压条件下砌体开裂后，砌体还能承受一定的压力，开裂荷载与极限荷栽之比在50％-60％左右，加气混凝土砌体延性较好，有一定的安全储备,在弯曲和沿通缝剪切条件下，加气混凝土砌体表现脆性破坏。

| Abstract: | Through the experiment, the mechanical properties of autoclaved aerated concrete block and the axis compression strength, the bending strength and shearing strength are measured. The characters of crack and destroy features of autoclaved aerated concrete block masonry are discussed under different load conditions, and the load displace curves are also analyzed. The results show that autoclaved aerated concrete block masonry can bear certain pressure and also has a better ductility when block appears cracks. The ratio of crack strength to limited strength is about 0. 5 -0. 6, thus there is some safe capacity. The autoclaved aerated concrete block masonry is obviously brittly damaged under the bending force and shearing force. |
