Steel construction - Fatigue verification according to Eurocodes

The numerical designation assigned to a particular constructive detail for a given direction of stress to indicate the fatigue strength curve to be applied to evaluate its resistance (this number corresponds to the reference fatigue strength $\text{Δ}{\sigma }_{\text{C}}$ in MPa)

Fatigue loading

Set of action parameters based on representative load-events and described by load positions, magnitude, phasing and relative frequency of occurrence.

Equivalent fatigue loading of constant amplitude

Simplified constant-amplitude loading giving the same damage as real variable-amplitude load-events

Geometric stress, hot spot stress
