Abstract:This paper presents testing results of thirteen small-scale beamsstrengthened using carbon fiber-reinforced polymer composites tested under repeatedloads to investigate their fatigue behavior. The beams were strengthened usingdifferent thicknesses and widths of composite laminates to identify parameters thatwould generate different failure modes. Two predominant fatigue failure modes wereidentified through these tests: fatigue fracture of the steel reinforcement withsubsequent debonding of the composite laminate, or fatigue fracture of the concretelayer below the tension reinforcing steel (concrete peel off). Test results indicate thatpeak stress applied to the reinforcing steel in combination with composite laminateconfiguration are the main parameters that affect the controlling failure mode. Tests onlarge-scale components are required to verify the results presented in this paper.
