Medium-term life-cycle monitoring of random behaviour components of in-service pile-supported wharves
Résumé
In the Nantes Harbour, France, two recently built pile-supported wharves have been instru-mented in 30% of the cross sections where tie-rods have been installed. Tie-rods are identified by a risk analysis as fundamental components for two main reasons: the first being that their behaviour is very sensitive to building conditions and secondly they support a significantly great portion of horizontal loading due to ship mooring or wind loading on container cranes. This paper aims to assess the structural health from the information acquired by monitoring and its probabilistic analysis during post-building step but before complete service loading (no ship mooring). A decomposition of measured loads in tie-rods on polynomial chaos is selected. Response distribution leads to assess both the probability of failure (considering a limit state design criterion) and the medium-term evolution of steel corrosion (considering an acceptable corrosion level).
