To enhance the bending or impact resistance for RC beams, one of the methods is attaching carbon fiber sheets or reinforcement panels to the bottom surface. Since in this study, our interest lies on the continuous fiber composite (CFC) panel which has a multilayer structure, and its failure behavior is extremely complicated. In this study, numerical analysis for failure behavior of RC beam retrofitted by CFC panel under impact load was conducted. Several kinds of failure behaviors were classified on the basis of different combinations of bonding strength between layers.
