Abstract:The bond behavior between fiber-reinforced polymer (FRP) composites and concrete is a complex problem that is influenced by material properties, joint geometric configuration and the surrounding environment. The three fundamental bond-performance indicators of concern are interfacial fracture energy, bond-strength and debonding strain. This paper introduces a new semi-empirical model for predicting interfacial fracture energy (Gf) between externally bonded FRP and intact concrete in terms of the most influenti… Show more
