为获得生土砖砌体沿通缝抗剪试验方法和标准试件,对18个不同砂浆、不同抗剪截面面积以及不同砌筑方式的机制生土砖砌体进行沿通缝抗剪试验,得到机制生土砖砌体沿通缝抗剪强度,分析机制生土砖砌体的破坏形态、破坏机理以及抗剪强度的主要影响因素.试验结果表明:普通砖砌体沿通缝抗剪试验方法适用于机制生土砖,沿水平方向砌筑的6砖试件适合作为抗剪标准试件,复掺胶粉和纤维素砂浆砌筑的机制生土砖砌体具有较好的抗剪能力和变形性能,可应用于村镇低矮房屋的承重墙体.
In order to get the shear test method and standard specimen along the through-seam of earthen brick masonry, 18 different mortars, different shear cross-sectional area and different masonry methods were used to carry out shear tests along the through- The mechanical properties of the masonry brick along the through-seam are obtained, and the failure modes, failure mechanism and shear strength of the masonry brickwork are analyzed.The test results show that the shear resistance of the common brick masonry along the through- The method is suitable for the mechanism of raw earth bricks. The 6 brick specimens masonry built in the horizontal direction are suitable as the standard specimen for shear resistance, the mechanism of masonry mixed powder and cellulose mortar has better shear resistance And deformation properties, can be applied to the bearing walls of low houses in villages and towns.
