Abstract

As an important component, the bond behavior of carbon fiber-reinforced polymer (CFRP)–concrete interface for a reinforced concrete (RC) beam is very significant. In this study, a theoretical model was established to analyze the flexural behavior of CFRP-strengthened RC beams, and the CFRP–concrete interfacial bond–slip relationship under hygrothermal environment was unified into one model. Two failure criteria corresponding to two types of failure modes, i.e., concrete crushing and intermediate crack (IC)-induced debonding, were developed. Through the theoretical model, the flexural behavior of deflection, interfacial shear stress distribution and ultimate load of a CFRP-strengthened RC beam under hygrothermal environment were obtained and predicted. Moreover, the theoretical model was verified by test results. The results showed that the hygrothermal environment had a significant impact on the CFRP–concrete interface behavior. Compared with the control beam without hygrothermal environment pretreatment, the deflection and ultimate load of the strengthened RC beam decreased by 51.9% and 20%, respectively.
