为了研究污泥页岩多孔砖砌体的本构关系,提出了一个待定系数的本构关系表达式,通过对砌筑的6组共36个砌体试件进行抗压试验,结合试验数据,确定了待定系数,得到本构关系表达式。通过与其它研究者提出的本构关系式对比结果表明,文中得到的本构关系式与这些本构关系式上升和下降段走势基本一致,且符合性较好,可作为反映污泥烧结页岩多孔砖砌体受压的应力-应变关系。
In order to study the constitutive relation of the masonry shale porous brick masonry, a constitutive relation expression of the coefficient to be determined is proposed. Through the compressive tests of 36 masonry specimens of 6 masonry units in combination with the test data, Determine the coefficient to be determined, to obtain the constitutive relation expression. The results of comparison with the constitutive equations proposed by other researchers show that the constitutive relations obtained in this paper are consistent with those of the ascending and descending stages of these constitutive relations and are in good agreement with each other. Stress - Strain Relationship of Porous Brick Masonry.
