In order to realize these weight lightening, structure was used to high strength thin plate. If thin plate structure is used, buckling about compression is happen so we should consider buckling. Commonly, we use the girder with stiffener to prevent shear buckling but if we use corrugated web, it can be the role of stiffener to buckling This study is developed of program about optimum problem using structure design process and real-valued genetic algorithm. For the optimum design, the objective function is defined weight of sinusoidal corrugated web and conduct by optimization. The program is analyzed by example.
