The author presents the optimum weight design of indefinitely long plate with reinforcements which are of flat-bar type or T-bar type. In this optimizaiton, it resulted that in case the both sides of the plate and the both ends of the reinforcement are simply supported the optimum interval of the reinforcements is such small as 1.5% to 2.4% of span length of the reinforcement and the plate with T-bar is lighter than that with flat-bar. And also in some cases o that optimization the thickness of the plate and the web plate of the reinforcements is so thin, if minimum thickness is not applied, that we cannot work with the plate in welding or we cannot find in the metal standard sizes. However, in the numerical calculation in which minimum thickness is applied to the plate and the web of stiffeners, the optimum interval of the reinforcements are reasonably wider than the above case.
