The around 485 m long, double-tracked and semi-integrally designed structure crosses on two separate superstructure and up to 80 m high Y-supports the Filstal valley. It has a main span width of around 150 m and is on both sides connected to tunnels.
The structure is built as single-web T-beam cross section on a launching track and on up to 80 m high temporary supports. The raking supports of the Y-supports are concreted afterwards and connected monolithically to the superstructures. Certain aspects of the bridge lead to exceptionally high requirements regarding the design, work preparation and construction and fabrication processes; these aspects are the high axle and breaking loads typical on railway lines, the future speed of 250 km/h on the ballastless track superstructure combined with the concept of a semi-integral bridge, the Y-supports with very flat diagonal struts and the difficult topographical and geometrical boundary conditions
A successful synthesis of challenging architecture and energy efficiency
The Energy Efficiency Centre was promoted by the Federal Ministry of Economy and Technology in the framework of the research focus EnOB (Research on optimised construction) as well as by the Free State of Bavaria.
Main goal of this building is to use new, innovative and efficient materials, systems and technologies and to verify by means of example their application within the building stock as well as on new buildings, to demonstrate them and to subject them to monitoring. The load-bearing structure (concrete and steel) was designed by SSF Ingenieure as BIM isolated application. New energy storage solutions to provide heating and cooling required an interactive and integral collaboration between the architects, building services specialists and structural designers.
