[en] This research consists of assessing and updating the remaining fatigue life of hydraulic steel structures when a fatigue crack has been discovered or is postulated.
Due to constraints linked to inspection practices, cracks are generally rather large when detected. The research aim is to provide an optimum planning of repairs, in the best conditions for different input data.
The study targets optimization of inspection schedule based on probability of failure, repair policies and cost of repairs. Risk-based inspection and maintenance of a hydraulic steel structure are performed based on a critical component or multiple critical components.
The study provides an innovative approach for calculating the reliability of hydraulic steel structures, giving strategies and solutions to mitigate risk under corrosion and fatigue fracture failure.
The influence of general corrosion and pitting corrosion for assessing and updating the remaining fatigue life of hydraulic steel structures are included in this research.
