This paper describes both experimental and FEM analytical studies on performance evaluation of RC beams bonded with FRP sheet considering putty lining between concrete surface and FRP sheet, Young's modulus of epoxy adhesive and FRP sheet material (Carbon or Aramid fiber). Loading tests on RC beam specimen and bond tests were performed and differences in performance considering these factors were evaluated. The constitutive law of spring model between concrete surface and FRP sheet was evaluated from the bond tests as the cut-off model for relationship between bond force and relative displacement. And this model was applied to FEM analysis of RC beam, and its suitability was verified through comparison with experimental results.
