Das Ottendorfer Viadukt - Entwurf und Ausführung einer außergewöhnlichen Stahlbogenbrücke

The Ottendorfer Viadukt - Design and execution of an exceptional steel arch bridge.

Due to the bad condition of the old railway arch bridge Ottendorfer Viaduct at the route Riesa-Chemnitz and to obtain the route availability the renewal of the railway overpass was required. According to the shape and functional specifications the bridge was designed as an arch structure stiffened by a framed substructure with a total length of 90.95 m and an arch width of 74.95 m. The central structure is formed by a bridge beam suspended from flat steel hangers connected with the overrunning arch. The arch is going through the bridge beams and forms with his stalks an additional supporting framed substructure. Because of this complex structural behavior the bridge is an exceptional engineering object. The special structure was carried out at the Deutsche Bahn for the first time and presents the Ottendorfer Valley with a highly aesthetic landscape mark. This paper reports on the design, the execution and selected static details of the bridge building.
