STUDY ON INTERFACIAL BOND-SLIP RELATIONSHIP BETWEEN HSSWM-ECC AND CONCRETE

  • 摘要: 良好的界面黏结是保证高强钢绞线网增强工程用水泥基复合材料(HSSWM-ECC)与混凝土协同工作的前提,其界面黏结的有效程度决定着HSSWM-ECC材料性能的发挥。为研究HSSWM-ECC与混凝土界面黏结性能,以混凝土抗压强度、界面黏结长度、黏结宽度和界面处理方式为参数,对设计制作的9组27个梁铰式试件进行了界面黏结性能试验。试验结果表明:界面黏结-滑移受力过程呈现明显的两阶段特征:非线性上升段和下降段。基于试验结果,探究了HSSWM-ECC与混凝土间界面黏结破坏特征和受力机理,构建了考虑各参数影响的界面黏结-滑移关系模型;采用微段分析法对模型特征参数进行了分析,结果表明:所建模型及特征参数计算与试验结果吻合良好,可较好表征HSSWM-ECC与混凝土界面黏结-滑移关系力学行为。
