本文讨论了由压缩试验得出的砌体特性。研究了应力-应变关系和正交各向异性弹性在砌体中的适用性。结果表明，在荷载作用下，混凝土和硅酸钙砌块砌体或多或少表现为线弹性材料，特别是在工作荷载作用下，混凝土和硅酸钙砌块砌体表现出非线性行为，而粘土砖砌体在破坏前一直保持线弹性。同时，混凝土砌块砌体可视为各向同性，硅酸钙砌块和粘土砖砌体可视为各向异性材料。在试验结果的基础上，提出了一套简单的砌体特性之间的线性关系，供实际使用。
This paper discusses masonry characteristics derived from compression tests. The stress-strain relationship and the applicability of orthotropic elasticity to masonry are examined. It is concluded that masonry behaves more or less as a linear-elastic material, in particular for working loads (loads up to 30% of the failure load); for higher loads concrete and calciumsilicate block masonry exhibits a nonlinear behaviour, while the clay brick masonry remains linear-elastic up to failure. At the same time concrete block masonry can be considered as isotropic, and calcium-silicate block and clay brick masonry as orthotropic materials. Based on the test results, a set of simple linear relationships between masonry characteristics is proposed for practical use.
