Axial beanspruchte Sandwichelemente in rahmenlosen Konstruktionen

Axially loaded sandwich panels in frameless buildings.

Traditionally sandwich panels are used as unidirectional spanning flexural members transferring loads to a substructure. As a recent development, sandwich panels are used to design small buildings without substructure. In this application the panels are not only used as cladding element but also for load transfer and bracing of the building. A design model for axially loaded sandwich panels, which also considers creeping effects, is presented. Additionally the basic failure modes at the area of load application are illustrated and a mechanical model is introduced.
