混凝土普通砖砌体受压应力-应变曲线试验研究

Experimental study on stress-strain curves of compressive solid concrete brick masonry

依据混凝土普通砖砌体的抗压试验,对其砌体结构的整体变形进行分析,对混凝土普通砖砌体的应力-应变曲线、试件破坏过程及破坏特征等进行了系统的研究,提出适用于混凝土普通砖砌体受压应力-应变曲线的表达式为:σ/fm=6.4(ε/ε0)-5.4(ε/ε0)1.14,为混凝土普通砖砌体替代实心黏土砖的推广应用打下了基础。

Based on the compression experiment of solid concrete brick masonry, this paper analyzes the unitary deformation of masonry structure and systematically studies their stress-straln curves, destructive process and characters, etc., a unified numerical expression of stress -strain curve applicable to compressive solid concrete bricking structures is put forward i.e.σ/fm=6.4 （ε/ε0）- 5.4（ε/ε0）^1.14 so as to lay a foundation for wide use of solid concrete brickink structures instead of solid clay ones.
