| Abstract: | The aim of this paper is to find the minimum cost of a ring-stiffened circular cylindrical shell loaded by external pressure. The minimum cost is given by the optimum dimensions, which can be calculated by an optimization technique. The calculation shows that the cost reduction has an effect reducing the shell diameter. The decrease in diameter restricted by a production constraint, that the inner diameter should be minimum of 2 m, to allow the welding and painting within the shell. This paper describes the optimization of this kind of structure considering cost calculation, which includes not only the material, but welding and painting costs as well. |
