Flexural buckling behaviors of centrally loaded columns of thin-walled stainless steels were experimentally investigated. Three types of sections, i.e., angle, H-shaped, and circular sections were tested. These specimens were formed from two grades of austenitic stainless steels designated SUS304 and SUS301L3/4H, whose specified yield strengths for design are 235 and 440N/mm^2, respectively. Test data of flexural buckling strength fairly well met the tangent modulus theory when tangent moduli of stub-columns were employed. Consideration of effective width associated with the reduction of stiffness due to local buckling gave a rational evaluation of flexural buckling strength. A column curve for design is proposed together with an appropriate safety factor.
