Serviceability assessment of the Góis footbridge using vibration monitoring
Footbridges are structures that may experience vibration amplification problems caused
by pedestrian and/or wind actions. Design codes deal with these phenomena limiting
the natural frequencies and the maximum accelerations expected. Aiming at taking into
consideration these dynamic phenomena, current procedures to evaluate the structural
performance of light-weight bridges based on experimental dynamic analysis are evaluated
in this study. To achieve this, the dynamic response of three pedestrians walking, running
and jumping was obtained. Maximum comfort limits of dynamic responses were then
determined. The results indicate that codes could overestimate the level of vibration in
this kind of footbridge(undefined
