Abstract (EN):
This paper describes the experimental and numerical study of the dynamic behaviour of a stress-ribbon footbridge
constructed at the campus of the Faculty of Engineering of the University of Porto, Portugal. This bridge has not
displayed any vibration problem, as yet, but significant levels of vertical oscillation have been observed under
pedestrian use. Therefore, a site observation programme was developed in order to assess the main dynamic
characteristics and levels of vibration of the bridge, to compare them with limit values recommended by structural
codes, and to validate a numerical model to be used in predicting the bridge response under extreme loadings.
