Abstract: Abstract Bridges and ships are key components of civil and marine infrastructure systems, respectively. Due to the nature of their in-service role, failure of such structures may lead to very high consequences. Preventing such failures requires rigorous design and life-cycle management techniques. In order to maintain satisfactory performance for these structures throughout their service life, various uncertainties associated with the design and management processes should be properly accounted for. Among the important design considerations for bridges and ships that highly depend on the proper identification of these uncertainties are the structural redundancy quantification and fatigue life assessment. In this chapter, quantification of redundancy and its integration into the design process of structural components are discussed. Additionally, the probabilistic fatigue assessment problem and the sources of uncertainties associated with the fatigue life prediction models are presented.
