摘要
带裂缝混凝土的拉伸破坏机理比较复杂,目前尚无合适或简便的力学模型和研究方法。借鉴复合材料力学分析方法,采用一种有限子层剪滞模型,并结合线弹性断裂力学,来分析带裂缝混凝土加固前后的应力分布,可为混凝土的破坏分析提供一种新的研究思路,也提供了一种新的关于结构解析解的研究方法和途径。
The mechanism of tensile failure of concrete with cracks is rather complex, so there are no suitable or convenient mechanics models and research methods. By learning the analysis method of composite material mechanics, using a kind of limited sublayer shear lag model and combining with linear elastic fracture mechanics to analyze the tensile failure of concrete samples with cracks provides a new research idea for the analysis of concrete destruction, and also provides a new research method or approach about structural analytical solution.
