摘要
介绍了现有砌体受压本构关系,并对其优缺点进行分析;针对29排孔和21排孔两类页岩烧结保温砌块砌体变形性能进行了分析,根据试验结果给出了该砌体受压应力—应变曲线,并提出了该砌体受压本构关系计算式和弹性模量计算式,最后给出了砌体泊松比建议取值。
The compressive constitutive relationship of masonry is summarized, and the advantage and disadvantage are analyzed. The deformation performance of insulation fired shale block masonry built up with 29 row holes and 21 row holes blcok is analyzed. According to the test results, the stress-strain curves of masonry are given, and the calculation formulas of compressive constitutive relationship and elastic modulus are proposed, finally the Poisson＆#39;s ratio is proposed.
