In this context, the MIREB (Management and Identification of the Risk for Existing Bridges) framework, developed by ETS, provides an integrated system for risk assessment and operational management of existing bridges. Within MIREB, a real-time dynamic monitoring system has been developed based on accelerometric sensors, aimed at the automatic identification of the structure’s modal parameters and the detection of significant changes in its dynamic behaviour. The system processes the acquired signals to extract dynamic parameters and allow for the identification of anomalies and the activation of alert mechanisms. A distinctive feature of the system is its interface with FEM numerical models, enabling the updating of structural models based on real data and the execution of engineering-level safety assessments under current conditions. This approach goes beyond simple monitoring by integrating dynamic observation with structural modelling to provide a more robust and timely evaluation of bridge health.
