Optimal design of elastic frames

Shape optimal design of elastic space frames with kinematically non-linear response is considered. A space frame structure is treated as to be assembl ed from several frame design elements each of them being defined as a skele ton Eying on a rational Bezier patch. The design variables may influence th e control points and weights of each patch, the cross-sectional quantities of beam elements as well as support parameters. Only a small set of design variables is usually enough to assure a good design flexibility.
