Glass roof with load bearing glazing

摘要

Within the last years the Institute of Building Construction, Technische Universit?t Dresden, has been decisively involved in the development of transparent space grid structures. These structures base on steel space structures, at which all steel members in the compression layer are replaced by in-plane load bearing glass panes. In 2009, the first glass roof of this new construction type was erected above the inner courtyard of the Berlin palace Reichstagspr?sidentenpalais. The roof consists of a single curved, double layer transparent space grid structure with dimensions of 14 m x 21 m. The load transfer in the compression layer is ensured by insulating glass units with regular dimensions of 1.80 m x 1.26 m. This contribution describes the concept, the structural design, the testing and the erection of the first transparent space grid roof with load bearing structural glass.
