Five kinds of CFRP composite reinforcement methods were established in this paper, combined with two kinds of CFRP reinforcement methods, flexural load bearing capacity of two-point loading was experimentally analyzed, then the failure characteristics of beams reinforced with various methods were obtained, based on the analysis of deflection, ultimate load bearing capacity parameter, the flexural rigidity of old reinforced concrete beam with cracks is increased significantly by CFRP composite methods, and the ultimate flexural load bearing capacity can be improved by 40% or more, thus greatly improving the integrity of old reinforced concrete beam, with remarkable strengthening effect, reference can be provided for the repair of beams of seismic damage in the future.
