Glass roof with load bearing glazing

摘要

Within the last years the Institute of Building Construction, Technische Universit?t Dresden, hasbeen decisively involved in the development of transparent space grid structures. These structuresbase on steel space structures, at which all steel members in the compression layer are replaced byin-plane load bearing glass panes. In 2009, the first glass roof of this new construction type waserected above the inner courtyard of the Berlin palace Reichstagspr?sidentenpalais. The roofconsists of a single curved, double layer transparent space grid structure with dimensions of 14 m x21 m. The load transfer in the compression layer is ensured by insulating glass units with regulardimensions of 1.80 m x 1.26 m. This contribution describes the concept, the structural design, thetesting and the erection of the first transparent space grid roof with load bearing structural glass.
