In the current Japanese Specifications for Highway Bridges, the design methods for compression members made of high strength steel are not coded. The design of such members is, therefore, carried out on the basis of the concept similar to that of mild steel, and the design concept is not rational for the members made of high strength steel. In this study, the ultimate strength of columns is investigated through a parametric study based on elasto-plastic and finite displacement analyses considering the inherent characteristics of residual stress distribution and stress-strain relationship of high strength steel. Then the buckling design method for columns made of high strength steel is investigated through the numerical results.
