Abstract (EN): This paper describes the work involving the implementation of a system to monitoring the vibration levels of the new Coimbra footbridge. This structure has some conception particularities which suggest some vulnerability to human induced vibrations. For that reason it was implemented some control devices composed by several TMDs. The monitoring system developed performs a permanent observation of the structures by analyzing signals from several sensors distributed along the deck. The time series acquired are processed and displayed on-line in a web site where it is also shown some frequency domain analysis. That information allows evaluating the maximum values of the acceleration at several points of the structure and, in ad-dition, the possibility to identify some dynamic parameters of the bridge.

Notes: abstract do artigo: The significant slenderness of the new footbridge over Mondego River, at Coimbra, has motivated the installation of a set of TMDs to control lateral and vertical human induced vibrations. This paper describes the main studies developed addressing specifically the design and implementation of the lateral TMDs and the most important results achieved from the dynamic tests developed to verify their performance.
