This paper presents the flexural strengthening effect of CFRP sheets on prestressed concrete (PC) beams having strands ruptured at the midspan. The increase in the number of sheets resulted in the reduction of tensile stress of the remaining prestressing strands. However, the increase in the number of sheets with insufficient sheet lengths did not provide a higher flexural strength because of the debonding from the sheet ends. The increase in the sheet lengths not only prevented the latter failure but also significantly improved the beam stiffness. More importantly, the debonding of the sheets was avoided by wrapping the transverse sheets for the whole beam span.
