Vervoort, E.M.C. Snijder, H.H. Maljaars, J. Publication year 2018 Abstract An existing theoretical model indicates that the behaviour of trapezoidal steel sheeting under combined web crippling and bending moment may be modelled by only the sheeting's compressed flange. Therefore, this paper presents finite element models that simulate only the compressed flange of the sheeting, applying a prescribed displacement field along the flange longitudinal edges to simulate the loading of the bending moment. Seven different and increasingly complex types of these finite element models of a flange are compared with verified finite element models of sheeting for (a) first yield load; (b) ultimate load; (c) yield line patterns; and (d) out-ofplane deformation patterns. It is concluded that a bottom flange only, or a flange with a rounded bottom corner and load bearing plate do not predict (a) and (b) for sheeting correctly. A moving load bearing plate improves to some extent the prediction of (d) and in combination with an imposed curvature on the flange also (a). Future work should investigate the introduction of large, webcrippling deformation sized imperfections in the flange models, also for flanges representing second-generation sheeting.
