The investigation on fatigue lives of reinforced concrete(RC)structures strength- ened with fiber laminate under random loading is important for the repairing or the strengthening of bridges and the safety of the traffic.In this paper,two methods are developed for predicting the fatigue lives of RC structures strengthened with carbon fiber laminate(CFL)under random loading based on a residual life and a residual strength model.To discuss the efficiency of the model,12 RC beams strengthened with CFL are tested under random loading by the MTSS10 testing system.The predicted residual strength approximately agrees with test results.
