This paper is concerned with a compression in the case of different eccentricities at the upper and lower ends of carbon steel square pipes with a circular hole in a short column range, supported by a spherical seat. It was found that breaking of these carbon steel square pipes occurred local buckling of the eccentric flat wall with a circular hole. The buckling strength decreased as the eccentricity and open ratio increased. Consideration has been given to the formula and diagram which were obtained by combination of the analysis based on the energy method with the experimental result. The measurement results show that the formula and diagram yield in good design data, and are in good agreement with those obtained experimentally for a short column range.
