摘　　要：研究MU10批次蒸压粉煤灰砖砌体24个试件的沿通缝抗剪性能,受力全过程破坏特征、破坏形态和极限荷载。试验结果表明:试件破坏形态表现为单剪面、双剪面和块体破坏,出现块体破坏是由于蒸压粉煤灰砖脆性大;单剪面、双剪面破坏其破坏面有较多连通气泡,表明砌体强度与砌筑质量有关。以试验数据为依据计算其标准值、设计值均低于GB50003-2001规范取值。The paper studies the shear performance, failure characteristics, damage characteristics and ultimateload of 24 specimens of MU10 batch of autoclaved fly ash brick masonry. The results show that the failure mode ofthe specimens perform single shear breakage, double shear breakage and block damage, and the block damage ofautoclaved fly ash brick masonry is due to brittleness; single and double shear breakage of the damage face havemore connected bubbles and poor quality of its construction. The calculated standard value and design value whichbased on the experimental data are lower than the GB50003-2001 standard value.
