This study evaluated the fracture strength of GFRP-strengthened RC beams caused by the debonding failure of the GFRP. The fracture strength of RC beams calculated using FRP debonding strains suggested by several main design guidelines were higher than those of experiments. The result might indicate the need of some reduction in the values of the debonding strain or the strength reduction factor.
