The failure modes and ductility of RC columns retrofitted by aramid fiber reinforced polymer sheets are discussed in this paper. In order to clarify the influence of fiber quantity and chamfering radius on the ductility of retrofitted columns, both cyclic loading test on 9 column specimens and nonlinear 3-dimensional FEM analysis were carried out. The followings are mainly concluded out of this investigation. 1) When existing RC columns are retrofitted so as to be more than 1.0 for both shear and bond capacity margins according to the AIJ design guidelines, they will get sufficient ductility. 2) The increase of the chamfering radius is effective for the transverse confinement together with the increase of the fiber reinforcement quantity.
