Title:
Abstract:	Für 15 typische Wellprofile werden die Schubfeldwerte nach der Verallgemeinerten Technischen Biegetheorie (VTB) bestimmt. Das Berechnungsmodell wurde bereits 1976 [5] vorgestellt. Die Krümmungen der Wellprofile werden durch Polygonzüge angenähert. Die Anzahl der Abschnitte bestimmt die Anzahl der zu lösenden Eigenwerte und Eigenvektoren. Die Lösung der Eigenwerte und eine geforderte Genauigkeit werden diskutiert. Für Trapezprofile wird eine ergänzende Untersuchung über den Einfluss von Stegversatz und Gurtsicken vorgenommen. Nach Kenntnis des Verfassers wurden diese Einflüsse noch nicht untersucht. Die Auswertungen von Beispielrechnungen für verschiedene Profile zeigen, dass das vereinfachte Berechnungsmodell weiterhin angewendet werden kann. Thrust field values for corrugated iron sheets - Including additional considerations for trapezoidal profiles. According to the Generalized Bending Theory (VTB) the thrust field values for 15 typical corrugated iron profiles are determined. The computational model has been presented already 1976 [5]. In the model the curvatures of the corrugated profiles are approximated by polygonal chains. The number of segments determines the number of eigenvalues and the number of eigenvectors which have to be solved. The algorithm for determination of the eigenvalues is described and the required accuracy of the solution is discussed. Considering trapezoidal profiles the influence of web offset and ripped chords is studied, too. By knowledge of the author these influences have been not yet investigated so far. The evaluation of results for various profiles shows that the simplified computational model can be used furthermore.
