In the present of paper, four experimental steel tubular columns with partial filled-concrete under reversed cyclic lateral load and constant axial load were numerically analyzed by finite element package ABAQUS. Under certain conditions of the radius-to-thickness ratio Rt and the slenderness ratio λ parameters, effect of filled-concrete height on ultimate strength and ductility of this type bridge pier was investigated. These numerical results of tubular columns with partial filled-concrete were compared with the previous experimental results. It was found that these numerical results agree with the experimental ones very well. And these load-displacement hysteretic curves, which were obtained from numerical model, indicated that filled-concrete height had greatly affected the ultimate strength and ductility of steel tubular bridge pier with partial filled-concrete.
