The paper presents a novel, object-oriented approach to structural modeling and analysis to enable interactive, virtual prototyping in the next generation of the design environment. It is believed that the interactivity of analysis of build-up structures can only be achieved by reusing results of component analyses, therefore, the applicability of data-based analysis to the 0-0 approach is investigated in this paper. An object in the 0-0 approach is a neurocomputing model of a structural component developed for a given set of parametrized design variables, loading, and "smart" connectors. Such connectors define how the given component is connected to the assembly, and what is the validity of such a connection. Since component models can be subject to affine transformations, a family of similar structural components is available for modeling. Neurocomputing models are used to enable data-based analysis, because they can relate any design variables and load conditions to the selected system response. The applicability of feed-forward and feature-sensitive neural nets is examined in this context. Object-oriented modeling is illustrated with design of linear and geometrically nonlinear beams with a single-point (SP) connector, and a multipoint (MP) connector is used for a selected problem involving the Next Generation Space Telescope (NGST).
