Sports hall FEG-Gymnasium
On the site of the Friedrich Eugens Gymnasium (FEG), a new sports hall with an underground car park and a recreational area is to be built for the city of Stuttgart to replace an existing, run-down gymnasium.
The sports hall is a two-storied reinforced concrete structure with a wide-span steel roof construction. The sports hall is on the ground floor with an adjacent outdoor playing field as well as viewing stands with an integrated equipment room. In the basement, besides the changing rooms, there is also an underground carpark. The building is constructed seamlessly as a monolithic structure.
The roof structure is a free-shaped steel construction. The main beams are trussed girders with spans of 32.5 m resting on slender, reinforced-concrete shear walls. In between these, secondary beams are spanned in a Z-shape, giving the roof a folding structure with skylights and dips. Large parts of the roof are covered with green plants for ecological reasons.
The foundations are made of single and strip foundations. Through back-filling with lean-mix concrete they are partly supported by the deeper, load-bearing gypsum Keuper layer.
