Abstract
Stiffened plates and shells are the most characteristic structural types for optimization since the number of stiffeners influences the cost significantly A previous study has shown that a plate stiffened on one side with open section longitudinal ribs subject to uniaxial compression is not so economic than a cellular one In the present article a plate orthogonally stiffened on one side is optimized The orthogonal grid of ribs is more economic since the transverse stiffeners increase significantly the overall buckling strength of the plate Constraints on overall buckling and on stiffener induced failure are considered The cost function includes material welding and painting costs
