Vibration measurements and modal identification were performed on a footbridge as part of the
commissioning tests. The deck presents a circular configuration, in plant, and is suspended from
eight cables connecting it to the extremity of a steel mast anchored to a concrete bulk situated on
the riverside. The dynamic measurements were aimed to control the force installed in the cables
during the tension operation and to characterize the dynamic parameters through output-only modal
identification techniques in order to calibrate a Finite Element model. At last, groups of pedestrians
crossed the bridge at various speeds allowing conclusions about the vibration amplitudes that can
be expected during real use of the bridge
