摘要
为了研究型钢与再生混凝土之间的黏结滑移性能,本文通过回归分析建立了考虑再生骨料替代率、混凝土保护层厚度、锚固长度3个影响因素作用的黏结滑移本构关系,并利用ABAQUS程序对拟合的黏结滑移本构方程进行数值模拟。结果表明:数值模拟能得到与试验一致的结果,证明该本构关系的合理性,为型钢再生混凝土黏结滑移机理分析提供一定的理论基础。
In order to investigate the bond-slip performance between steel sections and recycled concrete, a bond-slip constitutive model considering the replacement rate of recycled aggregate, the thickness of concrete cover and anchorage length is established by regression analysis.ABAQUS program is used to simulate the bond-slip constitutive equation.The results show that the numerical simulation results are consistent with the experimental results, which proves the rationality of constitutive relationship and provides a theoretical basis for the analysis of bond-slip mechanism of steel reinforced recycled aggregate concrete(SRRC).
