Abstract (EN): This paper presents experimental research aimed at addressing the fatigue behaviour of thin-walled cold rollformed steel sections, very commonly used in rack structures. This research is performed under the FASTCOLD-RFCS project, which aims to fill an existing gap on fatigue design rules. A new design S-N curve is derived from an innovative testing methodology, which supports the current revision of the Eurocode 3 (EN 1993-1-9). Additionally, a local fatigue approach, encompassing residual stresses from numerically simulating the manufacturing process and structural elastoplastic stress analysis supported by the Theory of Critical Distances, returned consistent fatigue life predictions for the tested profiles.
