This paper develops a method of structural optimisation for stiffened FRP panels allowing optimisation between cost and mass. The approach uses genetic algorithms for optimisation combined with elastic stress modified grillage theory for stiffener structural analysis and third-order shear deformation theory for the plate structural analysis. For top-hat stiffened panels, optimum designs following first principles and classification society rules are compared, showing considerable potential for cost savings by using a first principle approach.
