Mechanical Behavior of High Strength RC Beams Strengthened with FRP

Post-strengthening and retrofitting is a growing reality, as existing structures are required to meet the demands of modern society. Apart from the need to increase load capacity, upgrading of a structure may be necessitated through deterioration of the structure by corrosion or accidental damage, a change in the structural system, or to rectify initial design and construction faults. The purpose of this paper is to investigate the static behavior of reinforced concrete (RC) beams strengthened with FRP. Toward this end, a comprehensive test program has been set up and two series of strengthened beams have been tested. The results reveal a significant improvement in the serviceability and strength of the tested beams and demonstrate that the method is suitable for the rehabilitation of severely damaged structural members.
