This paper is concerned with an biaxial bending compressive experiment for the case of different eccerentricities at the upper and lower ends of carbon steel square pipes in a short column range, supported by a spherical seats. It was found that collapse of the pipes occurred as the local buckling of the flat walls by the side of eccentric and the stress decreased as the eccentric ratio increased. Consideration has been given to the formula for the buckling stress which is the combination of the analysis based on the energy method with the experimental result. The measurement results show that the calculated value by this formula is in good agreement with those obtained experimentally for the short column range.
