Concrete filled steel tubular structures (CFT) adopted in civil engineering works are increasing, especially in large scale of works because of high strength, deformation, toughness and so on. On the other hand, As a kind of strengthen measure for seriously damaged reinforced concrete piers of viaduct in Hansin-awaji earthquake of Japan in 1995,reinforced concrete piers were wrapped with steel plate. Then, a new kind of structure appeared, that is, reinforced concrete filled steel tubular structures (RCFT). In this paper, compression test and bending test with RCFT column and beam were carried out. Parameters of experiments were strength of concrete and steel, width-thickness ratio and rib of steel tube, and bar arrangement. And then, based on experimental results, study of strength of RCFT column and beam were carried out. Evaluation formula for column and beam were proposed and tested by experimental data and existed recommendations. As a result, the proposed evaluation formula can evaluate the strength of RCFT properly.
