Abstract
This paper investigates the effect of galvanisation on the fatigue strength of plates with welded transversal stiffeners. A series of 50 fatigue tests were carried out on welded details made of S355 structural steel. For comparison purposes, tests were performed on both hot dip galvanised (HDG) and uncoated joints. In addition, the influence of different cutting methods on the fatigue life was addressed. The experimental fatigue data was analysed, using different statistical methods commonly used in survival analysis. Both the normal distribution function, following the EN1993-1-9 approach, and the two-parameter Weibull distribution function, were considered. For the latter, different methodologies were employed to evaluate its key parameters. Finally, it was concluded that the resulting Wöhler curve for the HDG plates with welded transversal stiffeners matches the fatigue detail category80 of EN1993-1-9. The results of this study were used to propose new revisions of EN 1993-1-9, to extend its scope to galvanised steel details.
