Passerella Olimpica (object state)
A condition of an object at a particular time, reflecting the object's ability to fulfil it's requirements.

Object state
Summary
:
The Olimpic footbridge, built in 2006, has no sign of deterioration or occurring damage processes. The aim of the monitoring system is to control the structural behaviour over time and optimize the maintenance procedures. The Sacertis monitoring system, installed in August 2020, consists of 34 triaxial MEMS accelerometers installed on the deck and on a selection of stays. Prior information available were: drawings and design documents, results of the proof load test, n.2 previous dynamic measuring campaigns. A non-linear FE model has been calibrated based on the dynamic characterization (mode shapes and natural frequencies of the stays and the overall structure) and used to determine the warning and alarm thresholds levels. A near-real time alert system is active on the structure.
