The outstanding characteristic of the new design hotel Kameha Grand located in Bonn is the almost dematerialized and curved building glass envelope. The building envelope includes a multifunctional hall which enables a breathtaking view of the river Rhine. The hall in between the west and east wing reaches up to 21 metres height. It has a length of 55 metres and a width ranging between 24 and 30 metres. The main structure of the canopy consists of six beams made of 140 mm welded box profiles which are supported by 2 x 36 mm twin cables. The last two beams, which are facing away from the Rhine side, are braced with crossing x tension rods. The main beams have sliding blocks on one end along the beam axis in order to minimize temperature constraints. There are nine secondary beams perpendicular to the main beams.
