The building’s steel portal frames are positioned 320 cm apart and fan out in the curves. These strongly influenced the architectural design. The characteristic columns and beams are welded box sections with recessed flanges. The columns and beams are not treated with fire-resistant paint, in order to preserve the desired natural aspect of the steel. The inner space of the elements is filled with concrete, the cooling effect of which ensures a fire resistance of 45 minutes. The building’s crown is an impressive 15 5 m cantilevered floor on the southern side above the entrance. The cantilever is made possible by three storey-high frames, which are a mixture of truss and Vierendeel girder. Horizontal stability is ensured by concrete floors and stair-cores of fair-faced concrete. The floors act as assisting compression slab for the steel beams. Two bridges will connect the raised square to the other side of the river. Both bridges are welded steel structures. SCIA Engineer was used for both the building (global model, extraction and processing of calculation results) and the bridges (dynamic analysis in function of comfort and a second-order calculation regarding buckling sensitivity). New Library ‘De Krook’ and Pedestrian Bridges - Ghent, Belgium SE Contact Guy Mouton Address Koningin Astridlaan 225 9000 Ghent, Belgium Website www.studieburomouton.be Studieburo Mouton is a structural design office that has acquired a special position within the Flemish architectural landscape. The office is ready to be involved in the architect’s very earliest design stage. Its aim is to provide a stability study in which the interaction with the architect strengthens the design. Its main endeavour is to arrive together with the designers at an intrinsically superior design process and structure. Mouton envisages a powerfully expressed consolidation among partners that creates a superior final project. Studieburo Mouton bvba
