摘要
砌体弹性模量是砌体结构的基本力学指标,从3个不同的角度研究混凝土多孔砖砌体及砌体材料弹性模量取值的问题,即:利用试验统计资料,得到混凝土多孔砖砌体及混凝土多孔砖、砂浆的弹性模量表达式;由砌体轴心抗压试验,得到其受压本构关系并推导了弹性模量的表达式;基于混凝土多孔砖、砂浆的弹性模量推导了砌体的弹性模量。结果表明,这3种方法得到的表达式的计算结果与试验结果及现行规范的取值吻合较好,为混凝土多孔砖砌体结构的理论研究和工程设计提供了基础资料。
Elastic modulus of masonry is the basic mechanics index of masonry structure. The method of taking values of elastic modulus of concrete perforated brick masonry and its materials is studied from three different ways. That is： the formulae of elastic modulus of concrete perforated brick masonry, concrete perforated brick and mortar were derived on the basis of statistic regression of test results;the formulae of elastic modulus of masonry were derived on the basis of the constitutive relationship which was obtained from the axes compressive experiment： and the elastic modulus of brick masonry were derived from the formulae of elastic modulus of concrete perforated brick and mortar. The calculated results according to the three methods agreed better with the test results and current national codes. This has provided basic information for theoretical research and engineering design of concrete perforated brick masonry.
