Abstract
Combining fracture mechanics models for bidirectional crack growth with a Bayesian inference approach for taking into account the information acquired with structural health monitoring techniques is proposed as an analysis method for remaining fatigue life evaluation and inspection planning for fixed ocean structures. After providing a background for the proposed probabilistic analysis, as well as discussing the fundamental hypotheses and options, this paper exemplifies the method application to real data, from a case study. The method steps encompass global spectral fatigue analyses, a simplified probabilistic fatigue analysis, a deterministic fatigue analysis and a probabilistic fatigue analysis, including numerical experimentation with the Monte Carlo method.
