Abstrakt:

This urban pedestrian and bicycle bridge crosses the River Pisuerga in the historic city of Valladolid. A marked difference in the ground elevations between the riverbanks enabled a stress- ribbon type suspended footbridge. The total footbridge length is 110 m including the two anchor abutments and the central 90 m long suspended deck with a sag of only 1.72 m (1/50L).

To simplify the erection and the marked geometrical and material non-linear response, the supporting tensile force in this work is provided exclusively by means of a continuous 3600x35 mm S355 weathering-steel plate. This arrangement enabled us to place the concrete platform directly over the plate without a longitudinal collaboration between the two elements.

Due to the flexible response of these structures, special attention was paid to the dynamic analysis under pedestrian and wind variable loads. Detailed dynamic tests were carried out to verify that real accelerations matched the estimated analytical values.
