Abstract:	Stäbe mit Klasse 3-Querschnitt sind nach den Regeln des Eurocode 3 Teil 1-1 elastisch zu bemessen, woraus sich ein sprunghafter Übergang zur plastischen Bemessung von Klasse 2-Querschnitten ergibt. Der Beitrag legt als Ergebnis von Forschungsprojekten verbesserte Bemessungsregeln für Stäbe mit I-, H- und Rechteckhohlprofilen vor, welche eine plastische oder teilplastische Ausnutzung von Klasse 3-Querschnitten erlauben und sich vom Format her leicht in das Eurocode-Konzept eingliedern lassen. Damit können sowohl die Querschnitts- als auch die Stabilitätsnachweise für Stäbe unter Druck und Biegung in günstigerer und konsistenterer Weise geführt werden. Zugleich werden Anwendungshilfen in Form von tabellarischen Querschnittswerten sowie einer Bemessungssoftware für Querschnitts- und Stabnachweise vorgestellt. Improved design rules for beam-columns with class 3 cross-section. Members with class 3 cross-section - called semi-compact sections - are to be designed by elastic rules in accordance with Eurocode 3 Part 1-1. This leads to a sudden loss of capacity at the transition from the plastic design of class 2 sections to the class 3 sections. As a result of two European research projects, the present paper provides improved design rules for members with I- and H-sections as well as with rectangular hollow sections, which allow the utilisation of plastic or partly plastic capacity of class 3-sections and which can be easily incorporated into the Eurocode 3. As a result, the cross-section and the stability design checks for beam-columns can be performed not only in a more economic, but also in a more consistent way. Moreover, design guidelines with tabulated cross-section parameters and a design software for cross-section and member design are introduced.
