SIMPLE SUSPENDED BRIDGE IN OSLO | NORWAY
In colaboration with Gaute Mo AS and Solborj Architects.
Client: Oslo Komune
The simple suspended pedestrian bridge spans over the small river-valley near Ytre Ringvei, with 36 m. span, 2 meters wide and designed with smooth slopes in order to facilitate the crossing. The main structural elements to support the deck are the 2×2 walkway locked coil cables, forming a gentle parabola between the two abutments.
A system of steel framing elements formed by crossbeams every 1,5m, edge L profiles and crossing diagonals has been designed in order to transfer the loads from the decking and railings to the main cables as well as providing the necessary horizontal stiffness to the system. This system will also facilitate the erection of the bridge, as the elements can be prefabricated in shop, transported to site and placed in its final position without the help of large cranes, due to their lightness. This will minimize the impact on the natural environment.
The concrete abutments, stabilized with steel drilled micropiles act as permanent anchorages to compensate for the horizontal forces of the walkway cables and will transfer the load to the ground or the bedrock.
