[摘要] 对凹形砖砌体的强度等指标进行了分析对比，并对其特有的依靠塑性变位增大耗能、提高砌体整体抗震能力的机制进行研究，以此论证凹形砖砌体结构比普通砖砌体结构在强度及抗震方面的优越性，并赋予砌体结构全新的概念。

Abstract: The strength indexes of the concavity-brick masonry were analyzed and contrasted. And then, its specific mechanism was studied, which can magnify consuming energy through plastic deflection and enhance the whole masonry earthquake-resistant ability. By this study, it demonstrates that the concavity-brick masonry is superior than common brick masonry in such aspects as strength and earthquake-resistant, and also gives the masonry structure a brand-new concept.
Keywords: concavity-brick masonry; strength; earthquake-resistant consuming energy mechanism
