Inspections are an efficient means of enhancing the reliability of redundant structural systems subjected to fatigue. To investigate the effect of such inspections, we represent the deterioration state of a Daniels system by means of a probabilistic fatigue crack growth model of all elements, which considers sto-chastic dependence among element fatigue behavior. We include inspection results in the calculation of the system collapse probability through Bayesian updating of the system deterioration state. Based on this ap-proach, we calculate the collapse probability of a deteriorating Daniels system conditional on different inspec-tion strategies in terms of inspection coverage and inspection times. The acceptability of an inspection strate-gy is verified by comparing the calculated collapse probabilities with maximum acceptable system failure probabilities. This study is a step towards identifying optimal inspection strategies for redundant structural systems subjected to fatigue.     «
