    Pierre Mauroy stadium in Lille

    The steel roof of the stadium of Lille, whose total area is approximately 50,000 m², is generated by simple cylindrical and spherical shapes. The north and south areas of coverage are lowered to allow the opening of the mobile roofs. These are supported by two mega-trusses of 200 m length and 20 m high in the first project. The intervention of the engineering office Greisch in the «re-conception» of the steel frame allowed to reduce the height of the beams to16 m (technique of prestressed steel frame) so that the overall visibility of spectators in the stadium has been improved.

    In its final configuration, the stadium is able to welcome fully indoor or partly covered events thanks to a 120 x 80 m² roof opening.

    Our studies for the building methods have also allowed to suppress nearly all the welds on site in view to reduce the time necessary for the erection of the structure.
