Frost damage is a key deterioration factor for concrete structures in cold and wet areas which has been studied for several decades. For reinforced concrete (RC) structures, bond between reinforcement and concrete plays an important role and its degradation under freezing-thawing environment would affect the service life of the RC structures. This paper aims to develop a mesoscale simulation approach which could estimate and investigate the bond behaviors under the effect of frost damage. Based on the axisymmetric discrete element model - Rigid Body Spring Model, the micro-mesoscale mechanical strengthening/damaging effects by frost action were implemented to non-air entrained concrete and the bond interface. One-way pulling-out test was simulated and the calculated bond strength was compared with experimental results where good agreement was found.
