This paper presents a local bond stress–slip model for FRP–concrete interface (shear bond model). The shear bond model was derived based on a FRP stress–slip relationship at loaded end of pullout bond test, so that necessary measurement was simplified and the data scatter problem was minimized. The shear bond model needs only two material constants, interfacial fracture energy and interfacial ductility factor. The shear bond model was expanded to be bond stress–slip–FRP strain model to express cases with a short bond length. Both original and expanded shear bond models consider effects of mechanical properties of FRP, adhesive materials and concrete substrate. Besides the shear bond model, the prediction formula for interfacial fracture energy, effective bond length and bond strength for given anchorage length are presented.
