摘要

摘要: 碳纤维布(CFRP布)与混凝土构件的粘结能力是工程和试验中最关键的因素。结合有关试验从理论角度分析CFRP-混凝土界面的粘结滑移模型,推导有效粘结长度及粘结剪应力的计算公式,并将其计算结果与试验结果及其他文献进行对比,有效粘结长度公式计算值与其吻合较好。此外对粘结剪应力公式的进一步修正进行讨论。

Abstract: The key to engineering and experiment is the bond performance between CFRP and the concrete.It was analyzed the bond-slip model for the CFRP-concrete interface from the theoretical viewpoint and was deduced the effective bond length and the bond stress formula.The results by the formulas were compared with the results of experiments and other articles,the values calculated by the effective bond length formula were found to closely match with the results of experiments. The further amendments of the bond stress formula were discussed according to the experiences and experiments.
