Stuttgart 21 Main Station - Shape Development and Modelling of the NewStation Hall

摘要

The core of Stuttgart 21 is the new underground station with its characteristic "light eyes". Therailway tracks are rotated against the existing terminal station by an angle of 90 degrees, whichmeans they will be oriented transversely across the Stuttgart valley. This underground station isdesigned as a reinforced concrete shell structure, in such a way that the concrete shell is always incompression. Its "green cover" forms the link to a new municipal district on the location of thecurrent platform area. This paper describes the development of the shape of the shell structure, froma first soap membrane model over suspended chain models and digital CAD models to discretefinite element analysis models. The creation and modelling of the system, as well as the specialcalculations required are explained in some detail.
