This study is concerned with a comparison of the ultimate strength of stiffened panels as predicted by different codes/methods. Ten multi-span stiffened panels subjected to axial compression and combined compression and lateral pressure are considered. The focus is on failure modes, the effective width of flange plating and the ultimate strength of (multi-span) stiffened panels between transverse frames. The model uncertainty related to each code/method is estimated and the influence of imperfections on the accuracy of the methods is discussed. The influence of effective width on ultimate strength is tabulated. This benchmark study highlights two types of uncertainty: the model uncertainty associated with the model for strength prediction and the human factor uncertainty associated with computer codes for ultimate strength and especially their use.
