Abstract
The interface between crane (mechanical engineering) and crane runway girder (civil engineering), which is not explicitly defined, has repeatedly led to misunderstandings in practice in the past. Only the contact pressure between the wheel of the crane and the rail surface is verified by the crane designer acc. to EN 13001-3-3. The design of the crane rail itself is not covered by the crane design standards. On the other hand, the design of clamped rails acc. to EN 1993-6, that are subject of biaxial bending and torsion as a result of eccentric load introduction, has not been possible up to now because of missing design recommendations. This paper presents the current status of the design rules developed for the draft standard prEN 1993-6 and presents comparisons with realistic numerical investigations. In addition, an improved calculation model for the longitudinal stresses from concentric wheel loading is presented that is able to describe the actual load-bearing behaviour significantly more accurate in comparison to draft standard prEN 1993-6. Furthermore, a recommendation for a fatigue verification is formulated.
