Confinement generally is provided by lateral reinforcing in columns sections. If lateral reinforcing is insufficient, use of external devices such as FRP, steel or reinforced concrete jacketing is effective for columns retrofitting. In this paper steel jacketing with thermal post tension, as an external confinement, is proposed. In order to evaluate the efficiency of this method, theoretical is used. The theoretical approach is based on solving the plane strain equation of a section considering nonlinear behavior of concrete. Confinement pressure will be obtained by solving the equation at each step of applying axial load at the top of the column. To enter confinement pressure term in stress-strain relationship, approach proposed by Mander is used. Modified stress-strain relationship of retrofitted section by the proposed method is also capable of modeling cyclic behavior.
