| Abstract | An experimental investigation of the inelastic stability of
tapered steel columns is conducted through tests performed on seven columns of welded box-section. The primary variables are the slenderness ratio, the taper slope, and the ratios of the eccentricity at each end of the columns. The largest section of the column is 4" x 4" and the columns were made from structural carbon steel plates, the flanges being cut
from ⅟₂\'\' and the web from -3/16 " plates respectively. The effective length of four of the columns is 6 ft. - -3/16 in., and that of the other three is 7 ft. - 6¼ in. Specially designed end fixtures were fabricated to simulate simple supports. All the columns were tested under simple supports and loaded up to failure. The test results were compared with analytically predicted loads, where a good correlation was observed in columns in the lower range of the slenderness ratio. For columns in the intermediate
range, the discrepancies are comparatively larger due to the in fluence of residual stresses and initial crookedness which are prominent in this range but. are· not taken into consideration\' in the analytical predictions. No test was Garried out in the upper range of the slenderness ratio where the effect of residual stresses and initial crookedness are expected to be small |
