Abstract: The present work presents the experimental results aimed to assess the dynamical characteristics of a cable-stayed footbridge recently built in Terni (Italy). The assessment process involved both wind tunnel and full-scale experimental tests, and relied on the fruitful interaction between designers and academic experimenters. The wind-tunnel study investigated the wind-induced dynamical phenomena possibly affecting the structure. Then, the experimental work focused on assessing the actual dynamic features at prototype scale in order to confirm and/or to update the assumptions used for the design of devices to mitigate the undesired vibrations.
Keywords: wind tunnel tests, cable-stayed footbridges, vortex-induced vibrations, flutter, full-scale measurements, system-identification methods
