Nach einer Übersicht zu den Möglichkeiten der Nachweisführung und Ergänzungen zu den Imperfektionsansätzen für Bauteile werden die Ersatzstabnachweise systematisch dargestellt und eingehend erläutert. Es werden Hintergründe zu den Bemessungsregeln beschrieben sowie Parallelen und Unterschiede zur DIN 18800-2 aufgezeigt. Zur Eingrenzung des Umfangs und besseren Übersicht beschränken sich die Ausführungen auf Querschnitte der Klassen 1 bis 3. Die Anwendung der Bemessungsregeln wird anhand von Beispielen verdeutlicht. Member stability according to DIN EN 1993-1-1. With regard to the upcoming national implementation of the Eurocodes as DIN EN versions the following paper presents design rules for member stability according to DIN EN 1993-1-1. After the survey of different design approaches and additions to imperfections of structural members, the equivalent member method (Level-1-formulae) will be systematically described and explained in detail. Parallels and differences in comparison to DIN 18800-2 are shown in the context of respective design rules.
