It covers the new public transportation hub beneath the square. The canopy roof has a circular form with an outer diameter of 66 m. This cantilevered roof consists of a triangulated structure of steel box girders and a circular tension ring on the outside. During the design phase the structure was modelled in SCIA Engineer with beam elements. The cross sections were defined with the general cross section module. This allowed us to easily read and interpret its structural behaviour. The beams were optimized using an external, custom-made algorithm. At a later stage a more profound and detailed calculation was run. The complex hexagonal nodes, the intersection of the columns and the connections with the foundations were precisely modelled with 2D elements and integrated into the original model. The non-linear connection of the substructure to the existing foundation was also added to the same model. The use of the different design modules in only one structural model allowed for a fast and an easy interpretation and verification of the concrete and steel elements.

An active vision of civil engineering that integrates different disciplines is what motivates us. The foundation of a successful project is the synthesis of all contextual elements. We do not view the boundary conditions as obstacles but as fuel for our creativity. Our motto is ‘high engineering’ instead of ‘high tech’: effective engineering that adds value by eliminating the non-essential. Ney & Partners
