| Abstract: | The paper describes a dynamic study of a new slender footbridge currently under construction at the city of Coimbra, in Portugal. The bridge displays innovative characteristics and a complex dynamic behaviour. Numerical studies indicate the vulnerability to lateral and vertical vibrations induced by pedestrians, and the need to install control devices. A set of TMDs is proposed, and the corresponding efficiency analysed, considering the various uncertainties present in the analysis. |
