The geometric configuration in the double-layered structure is very required to be started from the conceptual design with low cost, high performance and quality. In this point, a structural-topological shape concerned with conceptual design of structure is important. The method used in this paper combines three optimization techniques, where the shape and physical dimensions of the shell structure and material distribution are hierachically optimized, with the maximum rigidity of structure and lightweight.
