要旨 This paper describes the experimental study on strengthening of pretensioned PC beams having 50% of strands ruptured using different amount of CFRP sheets. The flexural capacity was recovered up to 91.5% of that of the undamaged PC beam. However, the flexural capacity did not increase accompanied by increasing number of layers of CFRP sheets. The strength of the bonded sheets could not be fully utilized in the composite actions because of the premature failure. Besides, the debonding of CFRP sheets in the strengthened PC beams was affected by the amount of the sheets.
