A reliability-based methodology for considering corrosion effects on fatigue deterioration in steel bridges - Part II: Case study of Neka Bridge -
Abstract The methodology presented in Part I is examined on Neka Bridge, a railway, truss bridge in northern Iran. The study includes: considerations of climate and air pollution, extraction of the stress-time histories from the FE model, prediction of future traffic volumes in a probabilistic manner and assessment of the effects of MR&R actions on the deterioration profile. PDF of D is determined using Monte Carlo simulations, and the reliability profile is calculated from the performance function. The study shows that for a target reliability of 2.0, the fatigue life of the bridge is reduced by either 29% or 31% if dose-response function or qualitative-based y-t function is used, respectively.
