A Reliability-based Methodology for Considering Corrosion Effects on Fatigue Deterioration in Steel Bridges - Part II: Case Study of Neka Bridge -

다국어 초록 (Multilingual 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 trafficvolumes in a probabilistic manner and assessment of the effects of MR&R actions on the deterioration profile. PDF of D isdetermined using Monte Carlo simulations, and the reliability profile is calculated from the performance function. The studyshows that for a target reliability of 2.0, the fatigue life of the bridge is reduced by either 29% or 31% if dose-response functionor qualitative-based y-t function is used, respectively.
