Biege‐ und Biegedrillknicken von Sandwichelementen mit einheitlicher Knickkurve.

Flexural and lateral torsional buckling of sandwich panels using consistent buckling curves Sandwich panels are quick and cost‐efficient solutions in the field of modular and cold room construction, which allow buildings to be realized without load‐bearing substructures. This means that the sandwich panels are used as load‐bearing wall components taking over loads from other components and are therefore exposed not only to lateral but also to axial loads. With increasing building height, thus increasing slenderness of the sandwich panels stability issues govern the design. Different stability phenomena result from the position of the resulting load from the ceiling construction and the superstructures on top of it. Therefore, in addition to flexural buckling under centric and eccentric load the combined loading from flexural buckling and lateral‐torsional buckling becomes relevant. This paper presents a consistent approach for the derivation of buckling curves of axially loaded sandwich panels as well as the corresponding verification route, forming the basis of an easy and economic stability design of such components.
