通过试验研究了开槽蒸压灰砂砖砌体的抗剪强度,试验和研究分析表明:在砖的大表面开槽后,明显地提高了蒸压灰砂砖砌体的抗剪强度,其中开斜槽对蒸压灰砂砖砌体抗剪强度值提高最大,并基于开槽方式变化的对比研究提出了更合理的开槽方式。试验数据分析表明,开槽蒸压灰砂砖砌体抗剪强度值可采用现行砌体规范的抗剪公式和规范规定的蒸压灰砂砖或粘土砖砌体抗剪强度值。

The shear strength of slotted autoclaved sand-lime brick masonry is studied through experiments. The experimental and research results show that the shear strength of autoclaved sand-lime brick masonry obviously increases after the large surface of the brick is grooved, in which Open chute to maximize the shear strength of the autoclaved sand-limestone brick masonry, and based on the comparative study of the change of the slotting way, a more reasonable slotting way is proposed. Experimental data analysis shows that the shear strength of slotted autoclaved sand-lime brick masonry can be adjusted by the shear formula of the existing masonry code and the shear strength of autoclaved lime-sand brick or clay brick masonry specified in the code.
