Are welded stiffeners also taken into account for the fatigue design in CRANEWAY?


If stiffeners are welded into the runway girder, the corresponding notch design according to EN 1993-1-9, Table 8.4, detail 7 has to be considered for the fatigue design. This is implemented in CRANEWAY by creating additional stress points at the connection point of the stiffeners to the section. They can be adjusted manually in the settings for the notch cases depending on the geometry of the stiffener.

During the fatigue design of the crane runway girder, the design of the normal stress range is additionally performed in the newly created stress points for the x-locations on which a stiffener is provided.
