The structure has an intricate geometry that consists of a series of stacked toroids which are offset, on plan from floor to floor resulting in set-backs and cantilevers to the external elevation and to the inside face of the forum.
This footbridge in the city of Esch-sur-Alzette forms a direct link between the heart of the city and the green space of Parc du Galgenberg. Seeing the complexity of the geometry, we decided not to build a flashy full 3D model but to structure it into several efficient “local” FE-models.
The dismantling of the old suspended bridge required a precise non-linear analysis of each (de-)construction stage. “We had heard about SCIA Engineer features for such complex problems, we tested it and we decided that it is the right solution.”
