FEM analysis are performed to investigate the local behaviors of tubular steel towers reinforced by ring-stiffeners under two different loading conditions. The effectiveness of these results are evaluated through empirical studies using real-scaled models together with the preceding results regarding the tubular steels stiffened by both of ring-stiffeners and gusset plates. The derived conclusions are : (1) the effects of the axial forces on the yield strength of the stiffened steels are investigated. (2) the yield strength of a ring stiffener increaces under loads in a single direction while it decreases when loads are in multiple directions. (3) the stress distribution in ring-stifferners is able to be effectively evaluated by the proposed method.
