ABSTRACT
The 1915Çanakkale Bridge is outstanding and so is its Structural Health Monitoring. Designed and installed by Sixense upon the specification of the Client, the system will manage more than 1000 sensors. This monitoring architecture will allow to measure any external event happening on the Bridge such as strong wind, earthquakes, lightning, and heavy traffic. It will also record all the reaction behavior of the structure such as temperature, displacement, vibration, fatigue stresses. Amongst all the recorded data, dynamic records of such a slender structure is a key aspect. The acquisition system provided by Sixense will allow to record, compute, sample, and analyze a tremendous quantity of data related to the mechanical behavior of the structure. It will for instance allow rainflow counts of the stress cycles of the orthotropic slab in order to survey and prevent fatigue failure. But more than simply recording data for visualization and immediate maintenance, the system provided by Sixense will also allow predictive computations to model the future behavior of the infrastructure with regression analysis tools and will allow the owner of the bridge to anticipate the maintenance operations far in advance, out of critical service activity phases. This will increase the safety of the bridge, save money for the owner and allow this emblematic bridge to last for a very long time.
