砖墙体抗剪强度的计算,在我国现行规范中有两种计算模式,即剪摩公式和主拉应力公式。近年来,国内不少单位为编制和修订有关规范,曾进行了大量的砖墙体试验研究,取得了一批有价值的数据。据知新颁布的建筑抗震设计规范,仍将沿用主拉应力公式作为对砌体结构抗震强度的验算校核式。我们在开展有关课题的研究工作中,也进行一些单片墙体在静力反复作用下的试验研
In the calculation of the shear strength of a brick wall, there are two calculation modes in China’s current norms, namely the shear friction formula and the principal tensile stress formula. In recent years, many domestic units have conducted a large number of brick wall test studies and obtained a number of valuable data for the preparation and revision of relevant specifications. It is understood that the newly promulgated seismic design code for buildings will continue to use the principal tensile stress formula as a verification check for the seismic strength of masonry structures. We also carried out experiments on the monolithic wall under static repetitive action during the research work on related topics.
