Recently, carbon fiber reinforced plastic (CFRP) strips have begun to be applied in repair or strengthening of corrosion-damaged steel members. In the application of CFRP strips to steel members, bond defects are often caused by air bubbles because it is difficult to remove all the air bubbles from the adhesive layers. If bond defects have formed near the stress concentration points of adhesive (e.g. ends of CFRP strips or crack in steel members), the debonding shear stress may become higher than the case without defects. In this study, the influences of the location and size of bond defects on the debonding shear stress are examined by performing the finite element and theoretical analyses. Furthermore, the recommended area of inspection for bond defects is proposed.
