The structure consists of six frame supports made of pipe sections and welded I-beams made of galvanized steel, which support a double-curved PVC membrane. The roofing extends over the school sports fields of the Foyer de Charité de Châteauneuf-de-Galaure in the Drôme department. An integrated channel system in the I-beams and in the posts ensures unobtrusive drainage of rainwater. The model, modeled in RFEM, is subject to the copyright of AC Structures (AC Structures).
