This paper presents a theoretical study of high strength concrete filled square steel tubular columns with inner CFRP (carbon fiber-reinforced polymer) circular tube subjected to bi-axial eccentric loading. The new type of composite member is composed of a CFRP inner tube and a outer steel tube with concrete filled in the two tubes. The finite element analysis (FEA) is made by ABAQUS software on the behavior of high strength concrete filled square steel tubular columns with inner CFRP circular tube subjected to bi-axial eccentric loading. The results obtained from the finite element analysis were verified with the experimental results. An extensive parametric study was conducted to investigate the effects of steel yielding strength, concrete strength, steel ratio, slenderness ratio on the interaction curve N/Nu-M/Mu of column subjected to bi-axial eccentric loading. The parametric studies provide information for the development of formula to calculate the bearing capacity. The experimental failure load and the predicted failure load calculated by the formula showed good agreement.
