Global-local fatigue approaches for snug-tight and preloaded hot-dip galvanized steel bolted joints
Source abstract
Abstract
Abstract This work presents global and local fatigue approaches for snug-tight (common in rack structures) and preloaded bolted joints using thin hot-dip galvanized steel plates, where the zinc coating results in a low friction coefficient. Moreover, S-N data supporting the current revision of Eurocode 3 (EN 1993-1-9) is generated by considering remote and net stresses computed directly or by numerical analysis. Additionally, a master S-N curve based on elastic peak stresses is obtained encompassing the effects of the various tested conditions. Finally, a local fatigue life prediction based on the modified Morrow model combined with elastoplastic numerical analysis returns satisfactory results.
