CFRP retrofit in concrete members has various applications owing to its advantages of constructability and performance. The currently popular surface retrofit method frequently experiences reduction of attachment performance which is most important in CFRP retrofit. To resolve the problem, Near-Surface-Mounted Rertofit (NSMR) method was developed and being studied. In this paper, experimental and analytical study were performed to find the effect retrofit length and effective simulation method for the flexural behavior of RC beam strengthened by NSM CFRP. Nonlinear finite analysis as well as nonlinear sectional analysis for the RC beam were conducted by considering the bond characteristic in the connection and the results were compared to the experimental one. Test result indicated that the longer bond length the specimen had, the higher ultimate strength was shown. And the load-deflection behavior of RC beam strengthened by CFRP plate could be suitably simulated by using nonlinear sectional analysis approach.
