An experimental study is carried out to investigate the fatigue flexural behaviour of corroded RC beams strengthened with carbon fiber reinforced polymer (CFRP) sheets. The specimens are 200x120x1500 mm reinforced concrete beams. The results of this study indicate that the use of CFRP sheets for strengthening corroded RC beams is an efficient technique that can maintain the structural integrity and enhance the structural behaviour of such beams. The fatigue life of the CFRP strengthened corroded beams is found to increase by 1.24-1.56 times that of a similar unstrengthened corroded beam, but less than that of the uncorroded beam. The failure mechanism, fatigue of the steel reinforcement, remains the same in both strengthened and unstrengthened beams. Thus, this study suggests the possibility of predicting the fatigue life of the corroded beam with corroded steel bars fatigue models.
