Abstract

fiber-reinforced plastics (FRP) to infrastructure has become an attractive choice of structural ·and retrofit methods worldwide. load capacity concrete girders can be enhanced by the application of face of the element, but of these systems and can generally 'V'...., • .., ...... _...._ .... ;;:;.... concrete substrate. debonding mechanism is a local by stress intensities associated with stress transfer concrete and the laminate. This study examines design and existing damage parameters on debonding composite system and investigates a quantitative criterion governing these failures. Physical models of reinforced concrete beams are high-strength carbon fiber reinforced plastic sheets experimental The addition FRP is shown to increase ~i~iiii·-...~~ failure load of the beams, but specimens are to through of the retrofitted sheets the concrete substrate.
