Project description

New construction of the Erfurt Central Station. On a two-level concrete structure, which houses an underground parking facility and a service center with shops and restaurants, a two-section steel construction spans the tracks. The trusses of the side sections with a 20 m span and the three-chord trusses with a 65 m span each feature an arched design and are supported with an offset level by extending wishbone-shaped columns made out of pipe sections. The three-chord trusses with an overall height of 6 m made out of pipes mainly have bolted connections. The stabilization of the structure is achieved by bracings in the roof and the longitudinal walls in the center lines of the columns.
