Experimental Study on Debonding Load-Carrying Capacity of Cracked Concrete Strengthened with CFRP Sheet
This study conducts a series of experiments on cracked concrete strengthened with carbon fiber reinforce polymer (CFRP) sheet under three-point bending. The purpose is to investigate the effect of concrete crack on plate end debonding load-carrying capacity. 27 specimens were designed considering the pre-crack location, CFRP bond length and CFRP bond width. The results show that an abrupt change of the interface shear stress arises at the location of crack, and the debonding load-carrying capacity increases with the increase of CFRP bond length or CFRP bond width. However, when the concrete crack location is closer to CFRP end, the debonding load-carrying capacity is lower.
