Analysis
Summary
:
The structural assessment of the Fiume Po Bridge has been undertaken due to reliability checks required by the road operator, and reviewed by two independent international Engineering firms (as per Autovia Padana internal assessment procedure). As a result of the seismic assessment, the prestressed gerber deck will be replaced by a steel deck solution. The Fiume Po bridge has been subject to continuous monitoring since February 2020 as part of a consulting project (Sacertis Ingegneria srl), to control the structural behaviour over time and optimize the maintenance procedures until the deck replacement. A non-linear FE model has been calibrated using optimization algorithms based on the static load test and dynamic characterization of the structural response through long-term data analytics. The definition of the thresholds, for each sensor of the monitoring system, has been based on the simulation of significant damage scenarios causing a targeted reduction of the reliability levels.
