Viaduct (Galicia, España)
In Arc Steel Detailing develop all kinds of bridges and walkways.
We detail the most common orthotropic plate viaducts, formed by horizontal stiffeners and trapezoidal ribs.
Besides, we elaborate more complicated structures, geometrically complex, all of them with pre-camber and thickness according to the cross sections designed on the project.
In this case we took part in the detailed engineering of the Viaduct over the River Ulla in the Atlantic axis high-speed, mixed with a lattice of 240 meter of span. This bridge will hold the world record for the central span, beating Nautenbach bridge in Germany (208 m span)
Its structural typology is characterized by a mixed lattice of variable depth in the five main spans, with double composite action on areas of negative action.
Its total length is 1621 meters, a width of 14 meters and a board of 20,000 tons of steel and parts up to 17.5 meters of singing.
In Arc Steel detailing, we performed the detailed engineering of the opening number five.
