Ref: DNV-RP-F204 (July 2005), Sec. 3.4.1 – it is quoted as follows:
Quote
The effect of the Design Fatigue Factor (DFF) should be taken into account by reducing the allowable stress range by a factor (DFF)^-0.33
Unquote
I am confused whether to apply the above for all the cases (i.e. detail fatigue analysis required) or only for the cases which detail fatigue analysis is omitted.
Could somebody please shed light.
