Abstract: A recent and promising method for shear reinforcement of reinforced concrete (RC) members is the use of near-surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement. So far, numerical studies on the NSM FRP strengthening method have been rather limited. Furthermore, virtually no comprehensive analytical research is available on the behavior of shear-strengthened beams considering NSM FRP. This paper illustrates a numerical research program for shear reinforcement of RC beams with NSM reinforcement, which is intended to investigate individual parameters of numerical analysis and capture the effect of important issues. The proposed numerical analysis is validated against publishedexperimental results. The maximum load bearing capacity of the proposed numerical models was shown to be very good to the experimental results. As a result, the behavior of the FRP systems predicted by the analytical modeling was slightly harder than the values recorded experimentally; Probable differences in stiffness are discussed in this study. In general, comparison between numerical predictions and test results shows a desirable agreement.
