In the experiment, the previous three specimens have different degrees of debonding, and experimental values are significantly lower than the theoretical values, so the debonding of the adhesive layer can not be ignored in the actual engineering.
Conclusion The conclusion from this research can be outlined as follows: (1) The method of prestressed CFRP reinforcement of precrack beams can improve the load-carrying capacity and decrease the stress amplitudes of stress bar and concrete, which indirectly prolongs the fatigue life; (2) In the actual engineering, the fatigue failure of adhesive layer can not be ignored, which obviously affects the fatigue performance of members; (3) The soft bonding can significantly reduce the debonding stress of the adhesive layer, and effectively prevent the adhesive layer of the reinforcement members from premature debonding
