Abstract
Local stresses in crane runway girders with longitudinal stiffeners – experimental and numerical analyses. Crane runway girders with slender webs are often strengthened by additional longitudinal stiffeners to avoid local plate buckling of the web. This leads to an increase of local vertical bending stresses in the web due to eccentric wheel loads. These local stresses have a significant impact on the fatigue design of the flange-to-web connections and the required girder dimensions. In order to study this behaviour in detail, laboratory tests and numerical finite element calculations have been carried out on crane runway girders with longitudinal stiffeners at different positions of the web. Based on these results, the design model in EN 1993-6, that currently does not take into account longitudinal stiffeners, has been extended (based on a proposal from literature) to also cover additional stiffeners. Finally, the model is validated through a comparison with tests and numerical calculations.
