Erdberger Brücke (case study)
The Erdberger Bridge over the Danube Canal was built between 1968 to 1971. The bridge forms the heart of the traffic system with around 39,000 vehicles on the on the A4 and around 172,000 vehicles per day on the A23 (DTV Mo-Su March 2009) and thus represents an extremely sensitive and important interface for the operator. The total width of the supporting structure of 42.30 m allows, in addition to the six lanes in addition to the six continuous directional lanes. The bridge has a total length of 147 m. The load-bearing is ensured by a shell which is formed by a cylindrical barrel with a parabolic opening. On top of the two cylindrical shells of variable thickness rests a carriageway plate with a considerable cantilever and a free inner field of over 12 m in width. Between the bond of the carriageway slab and the shells, cylindrical hollow bodies were inserted. The supporting structure was not prestressed, with the central opening having a span of 73 m.
