“…There have been some investigations on fatigue performance assessment of steel bridges through low-cycle fatigue tests and theoretical strain-life method [74,75]. Jesus et al [76] presented crack propagation fatigue data from five Portuguese ancient metallic riveted bridges, and the strainlife fatigue data were correlated using both deterministic and probabilistic models. Up to now, only very limited amount of research has been conducted on fatigue life assessment of steel bridges based on the strain-life method, and the lack of such investigations is mainly because most of the fatigue issues in steel bridges pertain to HCF regime.…”

Fatigue is among the most critical forms of damage potentially occurring in steel bridges, while accurate assessment or prediction of the fatigue damage status as well as the remaining fatigue life of steel bridges is still a challenging and unsolved issue. There have been numerous investigations on the fatigue damage evaluation and life prediction of steel bridges by use of deterministic or probabilistic methods. The purpose of this review is devoted to presenting a summary on the development history and current status of fatigue condition assessment of steel bridges, containing basic aspects of fatigue, classical fatigue analysis methods, data-driven fatigue life assessment, and reliability-based fatigue condition assessment.

ABSTRACT. Europe has a number of ancient riveted metallic bridges, constructed during the second half of the 19 th century up to the middle of the 20 th century, which are still in operation. In this paper, a unified approach is presented to generate probabilistic S-N curves to be applied to structural components, accounting for uncertainties in material properties. The approach is particularly demonstrated for a plate with a circular hole, made of puddle iron from the Portuguese Eiffel Bridge. This paper presents an extension of the local strain-based fatigue crack propagation model proposed by Noroozi et al. The latter model is applied to derive the probabilistic fatigue crack propagation field (p-S-Np field). The probabilistic fatigue crack initiation field (p-S-N i field) is determined using a notch elastoplastic approach, to calculate the fatigue failure of the first elementary material block ahead of the notch root.

“…The use of S-N curves in the fatigue life prediction can be related to fracture mechanics based approaches. Additionally, probabilistic approaches can be implemented to handle the uncertainties associated to the materials or models as observed in the research works [10][11][12][13] that have been applied and compared with existing fatigue data from the Portuguese riveted metallic bridges. With the principle of meeting the most accurate estimates for the low-cycle fatigue regions, ranging from ultimate tensile strength to the high-cycle fatigue region, the Kohout-Věchet S-N curve is currently being proposed.…”

A new formulation of a Logistic deterministic S-N curve is applied to fatigue data of metallic materials from ancient Portuguese riveted steel bridges. This formulation is based on a modified logistic relation that uses three parameters to fit the low-cycle-(LCF), finite-life-and high-cyclefatigue (HCF) regions. This model is compared to the Kohout-Věchet fatigue model, which has a refined adjustment from very low-cycle fatigue (VLCF) to very high-cycle fatigue (VHCF). These models are also compared with other models, such as, power law and fatigue-life curve from the ASTM E739 standard. The modelling performance of the S-N curves was made using the fatigue data considering the stress fatigue damage parameter for the materials
