摘　　要：进行了墙体抗剪强度理论和公式的研究．将主拉强度理论与剪摩强度理论相结合，形成了一种新的强度理论，即拉摩强度理论．根据该理论，导出了墙体抗剪强度公式．给出了公式系数的确定方法，并确定了砖墙体的公式系数．将本文建议的砖墙体抗剪强度公式与抗震和砌体规范采用的抗剪强度公式进行了比较．比较结果表明：抗震规范公式值较小；砌体规范公式值较大；本文公式值介于两者中间．The research on the shear strength theories and formulas are made. The principal tensile strength theory is combined with the shear-friction strength theory, so that a new strength theory, tensile-friction strength theory, is formed. According to the theory, the shear strength formula of walls is deduced. The method of determining the formula coefficients is given, and the formula coefficients for brick walls are determined. The shear strength formula for brick walls suggested in the paper is compared with the shear strength formulas adopted in the earthquake-resistant and masonry codes. The results of the comparisons show that the values of the formula in the earthquake-resistant code are smaller, the values of the formula in the masonry code are larger, and the values of the formula in the paper are between both.
