This paper shows the current potential of Dynamic Bridge Testing techniques by presenting recent applications developed at the Millau Viaduct (France) and at the Humber Bridge (UK), and stresses the usefulness of Continuous Dynamic Monitoring, by describing fully automatic implementation in two recently constructed bridges in Portugal (Infante D. Henrique Bridge and Pedro e Inês footbridge, controlled with TMDs), enabling not only the automatic issuing of alert messages whenever some undesirable threshold is exceeded, but also vibration based damage detection using natural frequency shifts, after removing the influence of factors like temperature and traffic intensity on the modal properties.
