Abstract: A structural supporting truss (12) comprises an elongate rib (14) of resilient material connected to a web (16) of fabric material. The rib (14), in use, is elastically deformed to adopt a curved shape. The web (16) extends radially inwardly of the rib (14) along its length, the web (16) acting in tension to retain the rib (14) in its curved condition. The rib (14) may be made of a plurality of segments interconnected by hinges. The web (16) may comprise a plurality of panels (20). The rib (14) is subject to a compressive force. A remarkably stiff truss structure is formed such as may be used as a supporting truss for a tent of like shelter structure.
