This article describes the design and construction of an eccentrically stayed steel footbridge, built between the years 2009 – 2010 in access to the Port of Ferrol in Spain.
The footbridge named “AS” is a steel deck with S-shaped plan development of 205 meters. The main span, 60 meters long, and the two compensating spans are suspended off a set of eccentric stays that extend from one edge of the deck up to two leaned metallic pylons that will be the future gateway to the Port .
The deck, 3,768 meters wide, has a wooden platform of IPÉ wood, 2,40 meters wide, leaving empty spaces on both sides, making visible the steel structure, which consists of a metal tube, with cantilever beams of variable depths, attached to the opposite end by a smaller diameter tube. The deck is stiffened in plan with small diagonal tubes in tension.
The deck, therefore, presents great lightness and elegance that can only be surpassed by structures with stress ribbon typlology.
