通过对18个混凝土普通砖砌体试件受压试验,得到混凝土普通砖砌体在竖向压力作用下裂缝的发展特点和变形规律,建立了混凝土普通砖砌体抗压强度的计算公式。并对混凝土普通砖砌体试件从开始加载到破坏的全过程进行了分析,得到了混凝土普通砖砌体的应力——应变曲线、建立了适用于混凝土普通砖砌体受压应力——应变曲线的数学表达式,混凝土普通砖砌体弹性模量计算公式。可供混凝土普通砖的工程设计应用参考。
Through the compression test of 18 concrete ordinary brick masonry specimens, the development characteristics and deformation law of cracks of concrete common brick masonry under vertical pressure are obtained, and the calculation formula of the compressive strength of concrete common brick masonry is established. The whole process of the specimens from the initial loading to the failure of the ordinary brick masonry concrete is analyzed. The stress-strain curves of the ordinary brick masonry are obtained and the compressive stress-strain applied to the ordinary brick masonry is established. The mathematical expression of the curve, the calculation formula for the elastic modulus of ordinary concrete bricks. For the design and application of concrete common bricks.
