Epoxy - bonding a carbon - fiber composite plate to the tension face of concrete beam is an effective technique for repair and retrofit of concrete beams . in the first part of this paper , based on the fracture mechanics and the theory of beam , a theoretic model is proposed to analyze the shear stress in the adhesive between carbon - fiber composite and concrete . and then the closure - form solution for the shear stress distribution is drawn 本文的第一部分基于断裂力学与梁的基本理论,对碳纤维加固混凝土梁的粘结胶层以及粘结界面的剪应力分布进行了理论分析,得出了其理论解析解;讨论了碳纤维板的粘结长度、粘结厚度和粘结胶层的抗剪模量对界面剪应力分布的影响。
