This paper is concerned with a biaxial eccentric bending compression experiment for the case of equal eccentric at the upper and lower ends of carbon square pipes in the short column range, supported with spherical seats. An emperical formula for calculating the eccentric bending compressive buckling stress σ_<cre> of the carbon steel square pipes is presented as follows ; σ_<cre>/σ<cr>=1/(1+α_0), where σ_<cr>=axial compressive buckling stress, and α_0=factor of eccentricity and mean distance between the wall of the steel square pipes. The measurement reveals that the results calculated by this equation are in good agreement with those obtained experimentally for the short column.
