A new method for retrofitting RC columns having walls is proposed. The method is as follows: paste thin aramid fiber sheets on the column and bind the column with narrow aramid fiber sheets at large intervals. And, experiments on the shear strength, the deformation capacity, the bond performance and the applicability to short column were conducted. As a result, (1) the shear strength, the deformation capacity and the bond behavior could improve using the proposed method; (2) the mechanism of shear failure was different depending on the axial load.
