Cutting roll-formed steel C-section to stub columns will produce different extent of crosssection distortion along the lengths and cause additional initial geometric imperfections.
In this paper, minimum weight design of a hatch cover of box crosssection is made by geometric programming. The analytic optimal solution is obtained.
