The invention discloses a method for realizing crack resistance of a concrete beam member by optimizing ribbed FRP bars. The method comprises the steps of optimizing, manufacturing of a beam template,assembling of a mixed reinforcement cage and forming, the concrete beam member is reinforced by adopting the mixed reinforcement of the FRP bars and reinforcing bars, compared with single reinforcingbar reinforcement, the characteristics of high tensile strength and corrosion resistance of the FRP bars and good ductility of common reinforcing bars are sufficiently utilized, mutual complementation is realized, the defects of large deflection and crack width and insufficient ductility of the FRP reinforced concrete flexural member are overcome, the FRP bars are configured to the easy-to-corrode corner of the concrete beam member, the problem of steel bar corrosion of the reinforced concrete beam member and the defects of large deflection, wide cracks and brittle failure of the FRP reinforced concrete beam member are solved, the FRP bars are optimized, the problems that the bonding stress of the common ribbed FRP bars and concrete is small, bonding sliding performance is poor, the crackwidth cannot be effectively controlled are solved, and steel bars on the inner side are still likely to corrode are solved, the construction method is flexible, and both factory prefabrication and in-place casting can be realized.
