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
