The load-carrying capacities of cold-formed steel flexural and compression members are usually limited by yield point or buckling stresses that are less than the yield point of steel, particularly for those compression elements having relatively large flat-width ratios and for compression members having relatively large slenderness ratios.

Ramsey concluded that increasing the hull length to resulted in a L / D slenderness ratio ( the ratio of the length of the ship to the depth of her structure ) that caused excessive multi-axial bending and springing of the hull, and that the hull should have been structurally reinforced to cope with her increased length.
