Present paper proposes a supporting system for structural design of steel frame structures by using multi-objective genetic algorithm. Most of steel structures are composed of the standardized members produced at the factory. In order to take such situation into the process of structural optimization, the structural optimization scheme through the usage of genetic algorithm which can easily deal with discrete variables is presented. Furthermore, multi-objective optimal design method to obtain the Pareto solutions considering both structure's safety and its economy by using multi-objective genetic algorithm is proposed. Through the numerical examples, present design system is shown to be useful for designers as a valuable proposal tool especially in the beginning stage of the structural design.
