In order to certify the effect of the strengthening with carbon fiber sheets on the improvement of ductility of the reinforced concrete piers and to investigate the seismic properties after strengthening, static and pseudo-dynamic tests using reinforced concrete column specimens were carried out. From the experimental results, it was verified that the ductility of the piers can be improved by strengthening with carbon fiber sheets, and adequate volume and the necessary area of the carbon fiber sheets for the strengthening were obtained. Also, it was shown that the rupture of the carbon fiber sheets of the horizontal direction was occurred first at the corner of the column. From the results of pseudo-dynamic tests, it was confirmed that the piers strengthened by carbon fiber sheets could maintain well under the earthquake which had the maximum acceleration of 400 gal.
