摘要：
CFRP repairing is an effective way of repairing or strengthening notched steel beams. However, the debonding failure of CFRP repairing reduces the effectiveness of this reinforcement technique. The CFRP repairing debonding is the most dangerous failure mode to reduce the efficiency of CFRP repairing. In this paper, the surface based cohesive model and the finite element method are used to study the initiation and progression debonding failure of progressive debonding in notch damaged steel beams strengthened by CFRP plate. The effect of the patch length on the debonding is studied in this paper which can be used to optimize the geometrical properties of the composite patch.
