This paper is concerned with an axial compressive experiment on carbon steel thin-walled square pipes with a square hole in a short column range, supported with spherical seat. A digaonal line of the square hole pallels to the direction of the compressive load. It was found that the collapse of these carbon steel square pipes occurred as the local buckling of the flat wall with a hole. The buckling stress decreased as the open ratio increased. Consideration has been given to an empirical formula with the combination of the analysis based on the energy method with the experimental result. The result shows that this formula is in good agreement with those obtained experimentally for various ratio.
