RSCA - 09.009
Complete study of the stability of the extension of the stadium Constant Vanden Stock, RSCA.
In order to correspond to UEFA standards the Royal Sporting Club Anderlecht has decided to increase its stadium, located in full heart of Anderlecht, to reach the capacity of 30.000 spectators. The project includes the creation of a third ring of 15 steps, new rooms (reception rooms and VIP restaurants, press, etc) and a new roof for the entire stadium.
The renewing of the stadium surroundings, a new carpark and the rebuilding of the Simonet sports hall on the “ Hospital” site are also part of the project.
RSCA entrusted the complete mission of architecture, stability and special techniques to the grouping formed by the offices Jaspers-Eyers Architects, DDS&Partners, Ney&Partners and Arcadis.
The roof consists of a 40m cantilever.
But the stadium situation - in the middle of a residential district and in edge of the Park Astrid - imposes strict urban requirements. It was therefore necessary to reduce to the minimum the groundarea as well as the volumetric presence of the new roof.
We choose a solution where the tilting moment is taken over by to horizontal forces instead of two vertical forces.
The advantage is to avoid a double foundation line and therefore to obtain a stage as compact as possible.
We have also decided to make work the roof as a shell, in order to decrease the need a great structural height.
The consequence is that the shape of the roof must adapt to its internal forces. The shape is not arbitrary or an architectural choice anymore but the result of a “Form-Finding” process.
