The objectives of this research are to clarify the shear resistance mechanisms of R/C columns having wing walls retrofitted with continuous fiber sheets and to derive the formula to evaluate the ultimate shear strengths. In this paper, the bond behavior between carbon fiber sheets and concrete surface, which were attached using epoxy resin and the ultimate shear strengths of R/C columns having wing walls without retrofit are clarified and evaluated quantitatively. Then, the formula to evaluate the ultimate shear strengths of R/C columns having wing walls retrofitted with continuous fiber sheets is developed, being based on above results. Fairly good agreement between experimental and calculated results of the ultimate shear strength is shown.
