Bridges, Pedestrian Bridges

Weinbergbrücke – Federal Garden Show 2015 Havel Region

The new pedestrian bridge crosses the Havel river in an S-curve from the Weinberg-Park to the Optikpark. Angled steel arches support the superstructure at the longest span length located over the river and secondary channel. The hangers are not located as usual along the outer edge of the circular edge beam, but rather on radial cantilevers that almost reach the arch planes. Thus the resultant of the hangers is angled only slightly away from the angled arch plane, leading to reduced bending stresses within the arch. The arches terminate at the height of the superstructure and thereby allow for the horizontal thrust to be short circuited via a tie cable. Within the range of the arches, the bridge deck widens to allow for seating space. At the abutment the bridge deck is monolithically connected to the sub-structure, creating an integral structure.
