Engineering Office Ingenieursbureau Stendess N.V. Construction Period 09/2013 - 12/2013 The bridge over the N75 was built to eliminate dangerous crossings for cyclists and pedestrians. The bridge consists of a straight 60 m long access bridge (with four supports) and a curved cable-stayed bridge with a length of 90 m supported by 12 cables with two pylons with a height of 20 m. The bridge deck consists of a main tube (Ø 864) and an orthotropic bridge deck plate with transversal and longitudinal reinforcements. The bridge was transported to the site in pieces (27 m), positioned on temporary supports and welded on site. After the erection of the pylon and bridge deck, the cables were tensioned according a precise tensioning programme. After the tensioning, the main tube was filled with concrete as a counterweight (to avoid traction in the supports). The possibility of input and the use of graphical section was a big advantage because of the curved and continuously changing crosssections of the pylons. There was the limitation of the reactions on the bridge end supports and the simulation of the realistic behaviour of the cables. Because the linear calculations resulted in compression in the tension bars, a non-linear calculation was needed. A second order calculation was used to check the pylons based on a stability calculation. For the erection engineering, the different construction stages had to be examined. The dynamic behaviour of the bridge also had to be checked.
