The Fuldatalbrücke Bergshausen is a large, seven-span viaduct on federal motorway 44 , which spans the Fulda valley south of the city of Kassel near Bergshausen , a district of Fuldabrück . The structure is located between the Kassel-West motorway junction and the Kassel-South motorway triangle. In addition to the Fulda, the state road 3124 from the Fuldabrück district of Dennhausen to Kassel and the Fulda cycle path lead along under it . The existing steel framework structure is rarely found on motorway bridges today. The bridge with the roadway at the top lies a maximum of 55 m above the valley floor and is straight in plan.
history
The Südkreuz Kassel was planned as early as 1934 to connect the city of Kassel to the east via Eisenach with Dresden and to the west with Dortmund. In 1941 work began on the foundation of the bridge, but this was soon stopped due to the war. The building was continued between 1959 and 1962. A superstructure of the structure with one lane for each lane was built by a consortium of Aug. Klönne (today Thyssen Engineering GmbH), Philipp Holzmann and Teerbau GmbH (today Eurovia ). Nine years later, in 1971, the second superstructure followed with the expansion to two lanes. The construction costs amounted to 20.3 million marks. From 2006 to 2008, the structure was repaired for around 8.5 million euros to remove the greatest damage. At the end of 2008 it was decided to completely demolish and rebuild, as further repairs that were to be expected would no longer be economical. Then noise protection measures can be implemented that have been required for years by the residents of Bergshausen. Relocating the structure to the south is a possible variant. Until then, a speed limit of 80 km / h will apply on the bridge .
superstructure
The two steel half-timbered superstructures have the continuous beam as a structural system in the longitudinal direction . The two main girders of a superstructure are designed as a strut framework with a node spacing of 8.4 m. The system height is 6.0 m with a carrier spacing of 6.1 m. The total span of the seven-span bridge is 699.68 m, with individual spans of 79.20 m - 91.20 m - 107.84 m - 143.20 m - 107.84 m - 91.20 m - 79.2 m. The orthotropic carriageway slab , the first in Germany for a truss bridge, is 13.64 m wide in the southern superstructure due to the hard shoulder and 12.5 m in the northern one without hard shoulder. The plate is supported by cross members arranged perpendicular to the longitudinal direction at intervals of 2.8 m. The bridge is immovable in the longitudinal direction on the river pillar on the eastern Fuldaufer.
Foundation and substructure
Due to different subsoil conditions, the three western groups of piers and the associated abutment are deeply founded with driven piles , while the eastern substructures have a shallow foundation.
The pillars are made of reinforced concrete and have a rectangular two-cell hollow cross-section. The wall thickness is 40 cm with a constant pillar width of 8.0 m in the transverse direction. In the longitudinal direction of the bridge, the pier width is 1:42 and is 2.0 m at the pier head and between 2.63 m and 4.3 m at the pier base.
