Abstract
This paper is concerned with a compression experiment in the case of eccentric at upper and axial at lower ends on carbon steel thin-walled square pipes with various a/c ratios in the short column range, supported with spherical seats. An empirical formula for calculating eccentric compressive buckling stress "σce*" of the carbon steel thin-walled square pipes is presented as follows: σce*/σcr=1/(e/c) where σcr=axial compressive buckling stress, e=upper eccentricity, c=mean distans between wall, a=length. The measurement reveals that the results calculated by this equation are in good agreement with those obtained experimentally for the short column lange.
