Abstract
⺠A continuous dynamic monitoring system was implemented in a slender footbridge. ⺠It was used for serviceability assessment and health monitoring under operational conditions. ⺠During three years, acceleration levels generally satisfied comfort limits. ⺠Natural frequencies automatically identified were correlated with environmental factors. ⺠PCA and Novelty Detection were used to remove environmental effects and detect simulated damages.
