This paper is concerned with the compression experiment of carbon steel square pipes each with a circular hole in a short column range, supported with spherical seats. Consideration has been given to the diagram which is the combination of the analysis based on the energy method with the experimental result. The measurement reveals that this diagram is good design data, and is in good agreement with those obtained experimentally for a short column range. It was found that the agreement with those obtained experimentally for a short column range. It was found that the maximum compressive breaking load decreased as the opening ratio increased. Breaking of these carbon steel square pipes occurred as the local buckling of the flat wall with a circular hole.
