New framework for calibration of partial safety factors for fatigue design

In Eurocode standards, three verification schemes are proposed for fatigue design under variable amplitude loadings: 1) Based on constant amplitude fatigue limit; 2) Based on constant amplitude equivalent stress range at 2.10 cycles; 3) Based on accumulate ...

Using re-calibrated design S-N curves for fatigue assessment of road bridges

Alain Nussbaumer, Luca D'Angelo

Fatigue design of road bridges according to Eurocode standards can be based on damage accumulation, provided that information about loading spectrum is available. Characteristic values of fatigue resistance and load effects as well as partial safety factor ...

Measurement, Data Interpretation, and Uncertainty Propagation for Fatigue Assessments of Structures

Ian Smith, Claire Acevedo, Alain Nussbaumer, Romain Pasquier, James-Alexandre Goulet, Luca D'Angelo

Real behavior of existing structures is usually associated with large uncertainty that is often covered by the use of conservative models and code practices for the evaluation of remaining fatigue lives. In order to make better decisions related to retrofi ...

Calibration of partial safety factors for fatigue design of steel bridges

Alain Nussbaumer, Luca D'Angelo

The aim of this paper is to propose a new framework for assessment of fatigue partial safety factors with focus on steel bridges welded joints. Fatigue resistance S-N curves for constant amplitude (CA) and variable amplitude (VA) loadings are defined using ...

Probabilistic approach for fatigue evaluation of welded connections with application to road steel bridges

Luca D'Angelo

Fatigue analysis of steel bridges asks for consideration of welded joints. Traditional fatigue analysis of welded joints under variable amplitude loadings is based on the nominal stress approach, wherein constant amplitude (CA) S-N curves are used in combi ...

Fatigue Life Assessment of Existing Motorway Bridge

André-Gilles Dumont, Alain Nussbaumer, Marc-Antoine Fénart, Luca D'Angelo

The aim of this paper is to provide a fatigue-life assessment of an existing composite steel-concrete bridge within Switzerland. The Venoge bridge is a 219 meters length, four spans, four girder composite bridge, situ-ated on the Geneva-Lausanne Swiss moto ...
