Analysis

Summary

:

The Olimpic footbridge has been subject to continuous monitoring since august 2020 as part of a consulting project (Sacertis Ingegneria srl). The assessment has been undertaken due to reliability checks required by the municipality and a monitoring system has been installed to control the structural behaviour over time and optimize the maintenance procedures. A non-linear FE model has been calibrated based on the dynamic characterization (mode shapes and natural frequencies of the stays and the overal structure) and data analytics. The definition of the thresholds, for each sensor of the monitoring system, has been based on the simulation of significant damage scenarios that can cause a significant reduction of the safety and reliability target levels.
