Ultimate compressive strength and welding residual stress of high-tension steel stiffened plate was investigated experimentally by comparing with mild steel stiffened plate. As for residual compressive stress which was considered to have important effect on the ultimate compressive strength, residual stress in high-tension steel was less 0.10-0.15 σy than that in mild steel. From this difference, ultimate compressive strength of hightension steel should be expected to be higher than that of mild steel theoretically, but 12 test results of ultimate compressive strength showed no clear advantage of hightension steel. From these experimental results, this positive factor of residual stress should be considered to have not so much important effect on the ultimate strength.
