Title:
Abstract:	Bei Rahmentragwerken werden in den hochbeanspruchten Ecken häufig Vouten angeordnet. Die statisch-konstruktiven Vorteile gevouteter Stäbe können derzeit nur für wenige Sonderfälle effizient genutzt werden, da die für den Tragsicherheitsnachweis erforderlichen Angaben fehlen. Es werden Bemessungshilfen vorgestellt, mit deren Hilfe der Nachweis biegebeanspruchter Bauteile mit und ohne Vouten mittels Handrechnung geführt werden kann. Diese umfassen Hilfen zur Bestimmung des idealen Biegedrillknickmoments und Empfehlungen bezüglich der Wahl einer geeigneten Traglastabminderungskurve. Abschließend werden die vorgestellten Bemessungshilfen anhand von Versuchsergebnissen verifiziert. Lateral torsional buckling of I-sections with and without haunches - Design aids for a simplified check (part 1). In the highly stressed corners of frame structures often haunches are realized. Currently, the structural advantages of haunched members can be utilised efficiently for only a few special cases because of the lack of necessary information for the member checks. Design aids are presented that allow to perform the lateral torsional buckling check of members with and without haunches subject to bending by a hand calculation. These include aids for the determination of the ideal critical buckling moment and recommendations regarding the choice of an appropriate buckling curve. Finally, the presented design aids are verified by experimental results.
