This research addresses an integrated structure design method which integrates numerical analysis using finite element method and exact analysis method based on simple modeling of topological elements such as a beam, truss, and so on. The integrated design method contains three steps: (1) design of initial product structure, technical specification, and general arrangements, and (2) early optimization by finite element method, and (3) detailed optimization by exact analysis method. The first step consists of designing spatial slot and reinforcing area. The second step consists of mesh generation, calculation of stifeness matrix, and analysis of stress and strain. The third step consists of derivation of load for element, reference to design patterns, and calculation of detailed stress and strain. Through three steps, the detailed optimize structure is obtained.
