The new world-class Centre sportif de Gatineau has an architectural signature that is both strong and elegant. The Centre includes two buildings, one for the gymnasiums and the other for the swimming pools. The two main volumes are separated by the broad entrance hall measuring approximately eight metres, which is defined by volumes clad in wood and glass.
The space integrates the raised pedestrian crossing and offers a fluid and accessible route. This core ends on a roof-garden protected by the overhanging roofs of the two buildings.
The steel structure is distinguished by its sobriety. Most of the structural slabs are unidirectional with 450 mm thick reinforcement strips. A metal frame forms the roofs of the swimming pool and gymnasium, and is characterized by overhangs on all axes, with a length of up to 4 m. An acoustic deck, serving as a diaphragm, is supported by beams resting on the main trusses of the building, which consist of profiles. The frame of the stands was calculated to limit the vibration possibly generated by the spectators.
The building’s seismic analysis was performed using a medium ductility framing system, with tubular section bracing in tension and compression.
For this project, NCK provided complete structural and civil engineering consulting services.
