China's second largest travel Company has built a 20-storey high-rise with post and mullion facade in the center of Bejing. Two glazed cable net walls - with an almost invisible support structure - open the view to two spacious atria at opposite sides of the building; a glass roof spans over the atriums and their 9 m wide connection hall. The facade structure consists of a steel frame with horizontal beams every 14.4 m. Vertical cables are anchored to the steel frame at top and to the concrete foundation, and after pre-stressing also to the horizontal beams. Cable clamps at every point of intersection also act as glass fittings. The main girders of the glass roof span over 20 m at a distance of 8.1 m. The I-profile cross girders have a span of 8.1 m and - like the vertical cables of the facade - a distance of 2.04 m between them, and are suspended by a steel cable with round members as verticals. T-profile purlins support the glass panes and stabilize the cross girders.
