ShArc: A Shell that is an Arc as well

The ShArc is more than just a bridge from A to B; this bold design will become a destination in itself and a cultural landmark for the metropolitan city of Berlin. The tripod shaped bride is located at the intersection of the Spree with the canals Charlottenburg and Landwehr, connecting Charlottenburg with Moabit. The ShArc is a hybrid structure that combines the slenderness of an arc with the stiffness of a shell. The three members of the bridge are connected at the peak of the arc geometry. At that point the deck becomes a public platform where people can enjoy panoramic views of the surroundings.
In order to reduce the deck weight in that area and to maintain the open character, an opening has been created in the deck directing the pedestrian flows around the void.For a structurally effective geometry the deck is designed with a significant double curvature. In the cross-section the deck is a U-shaped half-pipe. The sides reach a maximum height at the middle of the span and also serve as a railing. In some areas, perforations are created to create views on the water and on the skyline, combining structural optimization with transparency.
