Experimental Study on Bonding Interface between CFRP and Concrete under Fatigue Load

Abstract:

Peeling along the interface between FRP and concrete under fatigue load is the common failure pattern for the RC structures strengthened with FRP. In this paper, five groups specimens were subjected to fatigue load to study the fatigue mechanism for bonding interface between carbon fiber laminate (CFL) and concrete. The Δσ~N curves for the bonding interface were derived from the experiments, the laws of strains and slip on interface were analyzed in this paper.
