Nesciobrug, Amsterdam

The Nesciobrug footbridge is a key feature of Amsterdam's new suburb of IJburg in the Netherlands. It carries the cycle link across the Amsterdam-Rhine Canal. The bridge was designed by Wilkinson Eyre Architects with engineering by Arup with Grontmij. The design challenges are discussed. The main span is a self-anchored suspension bridge with a curved steel box-girder deck. The curve of the cable complements the curves of the alignment. A single cable hangs between slim, single masts and single hangers in each bay support the deck. The design features bifurcation of each end of the main span, separating the cycle route from the pedestrian routes to the staircases at each end. Construction was planned around a single closure of the canal. The two columm bases are connected with a torsion box. The structural analysis for the design was performed using the GSA suite of programs from Oasys. The bridge was designed in accordance with Eurocodes. The vortex response of the bridge to wind was tested in an aeroelastic model of the bridge in a wind tunnel. The contract for construction was awarded to a consortium of Van Hattum en Blankevoort, Van Splunder Funderingstechniek and Heerema.
