The Steel Construction of the new Cargolifter Airship Hangar

Publisher Summary Nowadays a new generation of airships, the CargoLifter CL 160, is developed. Therefore, a new hangar for two airships is going to be built. With a span of 210 m, a height of 107 m, and a length of 363 m, the hanger will be one of the largest halls in the world. The central part of the hangar is of a cylindrical shape and consists of five steel arches covered with a textile membrane. At both ends of the building are the doors that consist of two fixed and six moving elements. They form a semicircle in plan and a quarter-segment of a circle in elevation. This chapter reports loading, analysis, and design. For the loading, a distinction has been made between permanent actions and normal and special variable actions. The permanent actions contain the weight of all the building elements. For the analysis, the building has been divided into three parts: the membrane, the cylindrical part, and the doors. The cylindrical part was analyzed as one large model, containing the five arches, the internal wind bracing, and the external torsional bracing as structural elements.
