Abstract (EN): The footbridge over the Carpinteira stream establishes a connection between two steep cliffs, at a height of 52.00 m above the water, having a length of about 220.00 m and being composed of three straight sections with different orientations in plan view, joined by circular curves and supported on four columns. In order to describe the dynamic behaviour of the footbridge, an ambient vibration test was performed, complemented by characterisation tests of the vibrations induced by pedestrians in the loadng scenarios assumed as critical for the structure. A detailed finite element model of the structure has also been developed for correlation analysis with the measured values. This paper shows the results of these tests and the main conclusions about the comfort level provided by the footbridge under the service conditions.
