The possible interpretation of DIN EN 1993‑6, Sect. 9.3.3 (1), that this eccentricity can only be applied to the web design, is incorrect according to Standards Committee NA 005‑08‑01 AA – Craneways (SpA to CEN/TC 250/SC 3). If centric load introduction cannot be prevented by special measures, it should also be considered for the fatigue design of welds.
Consideration of Eccentric Wheel Loading in Fatigue Design
In CRANEWAY, the eccentric wheel loading of 1/4 of the rail head width is used for the fatigue design of welds as well as for craneway girder design according to the National Annex of Germany and as of damage class S3. The eccentricity can also be considered for the fatigue design of welds.
