The purpose of this paper is to discuss data requirements for structural analysis, in order to clarify its dependence on the design process as a whole. The model generation capabilities of a state-of-the-art structural analysis system GIFTS 4, heavily oriented towards pre-and post-processing and computer graphics, is presented. The system is capable of generating points, curves, surfaces, and solids in a hierarchical manner. It recognizes that geometric definition is only a part, albeit a fundamental part, of the structural system definition. The geometric components are used as a reference geometry, upon which the user may define loading patterns, kinematic boundary conditions, material property variation and so on. It is in linking these items together with the geometry that a structural analysis becomes feasible. In presenting and discussing the data base requirements for a structural analysis in a consistent manner, the designer of a CAD system is presented with basic data requirements to be included in his data base design.
