Abstract (EN): The paper describes the studies developed for the assessment and mitigation of vibrations on a footbridge located in Portugal. The design of this steel arch footbridge with 60 m chord pointed to a lively behaviour that was investigated upon construction. The decision to install a passive control system based on two tuned mass dampers (TMDs) to mitigate vertical vibrations implied an experimental characterisation of the footbridge, the tuning of the TMDs and the verification of their efficiency, which are object of the present work.
