Abstract:	Der Wunsch nach einem vermehrten Einsatz von hochfesten, besonders dünnwandigen und/oder speziell geformten Hohlprofilen führte in den letzten Jahren zur Überprüfung und Revision bestehender, traditioneller Bemessungsregeln, u. a. für den Querschnitts- und Bauteilnachweis. Für die - nun deutlich häufiger auftretenden - schlanken Querschnitte der Klassen 3 und 4 stellen die als konservativ erkannten Bemessungsregeln teilweise ein Hindernis für die weitere Verbreitung der neuen Bauweisen dar. Das EU-RFCS-geförderte Projekt HOLLOSSTAB (2016-2019) setzte sich das Ziel, durch den spezifischen Einsatz der Kombination von einfachen numerischen Berechnungsroutinen mit experimentell validierten, analytischen Bemessungsformeln eine deutliche Verbesserung der Bemessungsverfahren zu erzielen. Das Ergebnis dieser Arbeiten ist die Generalised Slenderness-based Resistance Method für die Bemessung von Hohlprofilen unter allgemeiner Druck- und Biegebeanspruchung; sie wird in diesem Übersichtsaufsatz zum Projekt vorgestellt und diskutiert. New design method for hollow section strength and buckling resistances - the generalised slenderness-based resistance method The desire for an increase of the use of high-strength, very slender and/or specially formed steel hollow sections has led to the need for a review and revision of common, traditional design rules for these types of members, among them the rules for the cross-sectional and buckling resistances. Due to the more frequent use of slender (classes 3 and 4) cross-sections, the excess conservatism known to exist for this range of sections currently represents an obstacle for the wider use of more innovative structural typologies involving hollow sections. The EU-RFSC project HOLLOSSTAB (2016-2019) set out to develop new design rules with significantly improved results, thereby using a combination of bespoke numerical calculation tools and experimentally validated analytical formulae. The resulting design method, the generalised slenderness-based resistance method for the design of hollow sections under general compression and bending loading, is the subject of this review paper.
