Sports Centre Genk - 10.058


Complete mission for civil and structural engineering.


In 2008 the city of Genk organized an architectural competition for the extension of the renowned existing sports center designed by architect and engineer Isgour Paduart. The objective was to double the sports capacity of this listed modernist building. We won the competition with the proposal to establish the new program in a separate 80 m by 60 m building housing two multipurpose sports halls separated by a central area of support services and spectator zones. The innovative roof structure, which comprises of three parallel barrel vaults running in the longitudinal direction, integrates structure, acoustic measures, and natural lighting. (This particular form lends the new building its’ unique identity, and resonates with the slender concrete shell of the existing swimming pool’s roof.)

Specific features

The impact-proof acoustic ceiling, made of perforated steel panels, provides a uniform aspect to the entire soffit of the roof, enhancing the spatial experience of the sport areas. The 60 m wide transverse section of the barrel vaults is constructed using curved HEB300 steel profiles. The arches are inverted catenaries, providing optimum resistance to permanent loads whilst also allowing for the clearance demands of the different sport activities. The external edges of the outer arches bear on inclined concrete retaining walls, thus resisting the lateral thrusts. The two 30m intermediate spans, perpendicular to the arch ribs, cross the sports halls by means of triangulated structures between the arch ribs. These two continuous double trusses are supported on columns in the end walls and on pairs of internal columns, forming an 80 m long structure without movements joints. (Critical bolted connections have been designed in a way which ensures that accidental failure of one part of the roof does not lead to progressive failure of the entire structure.)
