Abstract	To develop a rational flexural reinforcing method for prestressed concrete (PC) beams with pretensioned Aramid Fiber Reinforced Polymer sheet (AFRPs), the new anchoring method is proposed. It is the concept of this method to rationally disperse the concentrated anchoring stress due to bonding the cross-directional AFRPs in the anchorage areas and to gradually relax the high strain caused at the ends of sheet due to applying the high-strain type epoxy-resin in the areas. Its applicability was confirmed by conducting static four-point loading test of the PC beams reinforced by means of the proposed method. From this study, following results were obtained: 1) applying the proposed anchoring method, predetermined pretensioning force of the sheet can be perfectly introduced into the beams without any mechanical anchoring devices; 2) the cracking and yielding loads, and the ultimate load of the PC beams can be upgraded due to bonding pretensioned AFRPs.
