【摘要】 通过三砖双剪面砌体模型试验研究了动力加载条件下的砌体剪压复合受力相关性。分析表明， 动力加载条件下的剪压复合相关性与静力加载下的相关性具有相似的规律。再次证实了关于抗剪强度的剪摩理论、主拉应力理论和Ｈｏｆｆｍａｎ 劈裂破坏理论所有的局限性，并提出了基于可靠度分析的动力抗剪强度计算公式更多还原

【Abstract】 This article researches the stress correlation of combined shear_compression of brick masonry by means of triplet brick model experiments.The results show that the stress correlation under dynamic loading is in much similar to that under static loading.It proves the Coulomb’s theory、Mohr’s theory and Hoffman’s theory on failure hypotheses.At the same time,a new equation based on reliability analysis is propossed.更多还原
