Flexural strength of autoclaved ash shale brick masonry was studied through experiments on 22 brick masonry specimens which were made from three kinds of mortar under bending moment. Failure characters and flexural capacity of the brick masonries were investigated. The result shows: the flexural strength was affected greatly by the masonry methods and construction quality. On the contrary, the flexural strength was affected slightly by the mortar strength. Basing on the investigative result,the formulae of flexural strength for the brick masonries were proposed.%通过对3种砂浆砌筑的22件蒸压灰渣页岩砖砌体试件的弯曲抗拉试验,对该砌体在弯曲拉应力作用下的抗拉性能进行了试验研究,分析了该砌体的破坏特征与弯曲抗拉能力.研究表明:砌筑方式与施工质量对蒸压灰渣页岩砖砌体弯曲抗拉强度影响较大,砂浆强度对砌体弯曲抗拉强度影响不明显.依据试验结果提出了该砖砌体弯曲抗拉强度的计算公式.
