The stadium of Madrid, which was completed in 1992 and destined to athletics, is made up of a single grandstand of large seating capacity set east from the pitch. As from the year 2004, the city council of Madrid has been promoting the development of an expansion project for this site so to convert it into a football stadium for 70,000 spectators.
The structure of the new stadium is mainly composed of large, radially placed rigid-frame structures which, together with the existing grandstand, configure a completely closed stadium. The statically determined, precast concrete steppings are placed on top of these rigid-frame structures.
Under these rigid-frame structures, there are reinforced-concrete or post-tensioned slabs which define the building’s above-grade and basement floors. The whole is surrounded by perimeter walls which constitute the building enclosure.
Finally, the stadium is covered with a fabric roofing designed by the engineering office Schlaich Bergermann und Partner.
