In this overview of loaded a longitudinally stiffened welded circular cylindrical steel shell is investigated. The halved rolled I-section stringers are welded outside to the shell. The simply supported belt-conveyor bridge is loaded by bending with a uniformly distributed normal load. The design constraints are related to the shell buckling, panel stiffener buckling and the maximum deflection of the bridge. The optimum shell thickness as well as the dimensions and number of stringers are sought, which minimize the cost function. The cost function includes the material, fabrication and painting costs. For the comparison an unstiffened shell is also optimized. The cost comparison shows that the cost of stiffened version is smaller than that of the unstiffened one only in those cases when the allowable deflection is strict enough.
