Nowadays, structural strengthening is highly required in the market; especially the strengthening with CFRP because of its convenience and effectiveness. However, there is a pricing problem of the CFRP and its adhesive, which are expensive materials. Therefore, researchers and Nontri Co., Ltd. desire to study the method of CFRP wrapping on reinforced concrete column just adequate to the need with limited material use. Many forms of CFRP wrapping on RC column were studied such as fully wrap, partial wrap in vertical and horizontal direction, partial wrap only horizontal direction and no wrap at all. The study shows that the partially wrapping in horizontal direction on RC column increase the column strength about 14%and increase column ductility due to the concrete confinement effect. The horizontally patial wrap can be another option for users if the strengthening requirement is mainly concentrate on the structural ductility not on the structural strength.
