Bridge health monitoring, structural assessment and dynamic response: overview and perspectives

An overview of the main recent techniques of Bridge Health Monitoring (BHM) is presented. The use of vibrations induced by artificial or natural loads is considered, together with ordinary (i.e. traffic, wind) or extreme events (i.e. seism, impact). The data can be interpreted by direct modelling or by machine learning routines in order to obtain advertises to a deeper investigation on integrity or serviceability of the bridge. A brief discussion on key gaps and perspectives is finally presented.
