Abstract

The fatigue performance of components in substructures of offshore wind turbine generators is decisive for the design. Current standardised fatigue assessment approaches neglect load history dependant material behaviour and estimate a linear dependence between stresses and strains. The present paper lines out basic theoretical considerations about effects of varying load sequences and shows investigations considering their relevance to welded spatial tubular joints in jacket substructures. All conducted investigations are based on the Uniform Material Law and on relevant technical guidelines for substructures of offshore wind turbine generators.
