This report discusses the method of evaluating ductility on existing reinforced concrete(R. C.) structure which is strengthened with H-shaped steel elements. From former reference, through experimental and calculating works, it is verified that the ultimate shear strength of strengthened R. C. frame can be simply obtained by the method of adding shear strength of the seismic steel element and existing R. C. frame on the basis of conventional calculation. Here, we also try to evaluate the ductility of strengthened R. C. with the same method, considering R. C. frame and steel frame , respectively. The ductility of steel frame is supposed to be more excellent than that of R. C. frame. So, ductility of strengthened R. C. is only determined by that of existing R. C. frame. In this report, we apply the means of the Guide to evaluate ductility of R. C. frame and then it is verified that the evaluating of safety can be got.
