摘 要:本着对砌体结构抗剪强度的直接预测要求,对砌体结构试件进行了受剪斜压试验和三轴压缩试验。试件使用了不同砂浆组合,将斜压试验数据和三轴压缩试验数据套入文献中的不同计算公式计算出砌体抗剪强度值,并进行了比较。试验结果表明,砌体抗剪强度取决于接缝砂浆类型,相对于受剪斜压试验,三轴压缩试验方法简单直观,试验结果更为可靠,更适合用于砌体结构的抗剪切试验。
Abstract: Based on the prediction of masonry shear strength by direct way, diagonal compression tests and triplet tests are carried out. The shear strengths of brick masonry specimen are calculated using the various formulas from references, and the experimental data from appropriate experimental tests and triplet tests are compared. The test results show that the shear strength of brick masonry walls is depends on the types of joint mortar, and the triplet test is very straightforward and can provide reliable data results, so it’s more suitable for shear strength experiment of brick masonry walls.
