S21 – Access walkways

A number of architectural alterations are being made to the state capital of Stuttgart as part of the Stuttgart-Ulm railway project. These changes include the construction of a new, underground, eight-track through station with a train shed that measures approximately 420 metres long and 80 metres wide. Three walkways allow passengers to access the new train shed from Stuttgart’s historic Bonatz building. These walkways consist of bridge-like reinforced concrete composite constructions with stairs leading down to the platforms. From a structural planning perspective, it is possible to split the walkways into two separate sections: a reinforced concrete composite section and a classic reinforced concrete section with infill panels made from precast reinforced concrete elements and glass bricks.
