Railway Bridge Grubental

Ebensfeld - Erfurt, new railway route, Germany, 2013

As part of the new high-speed railway route VDE8 one of the first semi-integral reinforced concrete bridges will be constructed in Germany. Slender reinforced concrete pier walls carry the robust double-webbed pre-stressed concrete superstructure. This allows a minimal structural height of 2.40 m. The structure consists of a joint- and bearing-less eight-field beam, with a sliding connection located at the superstructure to the abutment. The structural system of a beam supported by inclined struts will be constructed as a double-hinged arch with a pronounced apex, thereby creating the fixed point for the track beam. The slender arch segments spread slightly where they meet with the inclined abutment, which is also able to take the horizontal forces, thus endowing the structure with an elegant, dynamic appearance. The result is a robust and redundant structure with a minimal need for inspection and maintenance.
