ABSTRACT:
A building system composed of space-filling saddle zonohedra which fit together periodically and non-periodically into a variety of orderly and irregular looking space structures. The saddle zonohedra are composed of convex or non-convex saddle polygons and are derived from the infinite class of plane-faced zonohedra. The surfaces of the saddle polygons could be continuously curved surfaces or faceted polygonal surfaces derived from minimal surfaces. The surved surfaces could be flexible membranes or nets in tension used by themselves or in combination with space frames, or stiff shell-like surfaces, and the edges of the space frames could be hinged or fixed to others. Applications of the system include architectural and environmental structures, fixed or retractible space frames, decks or platforms, educational kits or toys, curved tiles, and saddle polyhedra nodes for space frames. The building system could be used in extra-terrestrial environments where saddle-shaped "floors", surfaces and enclosures provide interesting possibilities.
