One of the major tasks for the construction industries worldwide is rehabilitation of structurally deteriorated or functionally obsolete reinforced concrete structures. The major portion of the infrastructure is built from reinforced concrete and corrosion of reinforcing steel was found to be one of the principal cause of deterioration. The solution to this task has been proved by the use of externally bonded carbon fibre reinforced polymer (CFRP) strips to strengthen reinforced concrete structures. In this study, the behaviour of reinforced concrete beams strengthened with externally bonded carbon fiber reinforced plastic (CFRP) under fatigue load were investigated. The capacity of CFRP strengthened beams subjected to fatigue loads, fatigue characteristics of reinforced concrete beam strengthened by CFRP, fatigue life and behaviour of the reinforced concrete beam were studied. Data obtained from experimental investigations were statistically analyzed and valid correlations were obtained.
