Abstract of the Disclosure A roof formed from a self-supporting inflatable structure including a polyhedron frame made from tension cables interconnected and joining at nodes and an envelope surrounding the frame. Anchoring skirts extend from each node lines to predetermined lines on the panels forming the envelope. The polyhedron frame is such size as to provide an arch shaped roof covering an area to be covered, and when the envelope is inflated, and sufficient internal air pressure is therein maintained, all of the tension cables are under tension and the overall structure becomes rigid, stable and capable of resisting deformation caused by external forces applied to it.
