After the 1995 Hanshin-Awaji Earthquake, many researchers have energetically studied on the seismic behaviors of strengthened R/C columns by CFRP (Carbon Fiber Reinforced Plastics) sheet jacketing. Design equations for the strengthening of R/C columns using CFRP sheets were proposed on the basis of the above studies. However ductility improvement of horizontally excited R/C columns under high axial load could not be evaluated by these design equations. In this paper, the author proposes the evaluation method ofductility improving effect of CFRP sheet jacketing and steel plate jacketing on the basis of experimental studies. From these experiments, it has been clarified that the steel plate jacketing is more effective to improve the ductility of horizontally excited R/C columns under high axial load.
