In this study, in order to develop a CFRP rod/mesh embedded section thickening method for RC beams, we experimentally examined the bending/shear reinforcement effect of RC beams with CFRP rods/mesh. As a result, In the case of RC beams with bending and shear reinforcement by CFRP rod and mesh thickening, it was confirmed experimentally that a large increase in yield strength was obtained compared to ordinary RC beams. Moreover, as a result of examining by three-dimensional finite element analysis, the analysis result was able to reproduce the bending property of the experimental result. Furthermore, it was found from the analysis results that the adhesion constitutive law of CFRP rods greatly affects the increase and decrease of bending resistance of RC beams.
