Querkraftbeanspruchte Verbindungen von Sandwichelementen

Shear loaded fastenings of sandwich panels.

Sandwich panels are mostly used as components for enclosures. They are installed on a substructure and transfer forces to it. Because of the high in-plane shear resistance of the panels they can also be used for stabilizing single components and buildings as well as for transferring loads. The stiffness of the fastenings is smaller than the stiffness of the panels. Therefore for the stiffness of diaphragms made of sandwich panels not the stiffness of the panel, but the stiffness of the fastenings is decisive. So for design of shear diaphragms knowledge of the stiffness of the fastenings is mandatory. But up to now no general information or calculation procedures are available. A mechanical model for determination of stiffness and load bearing capacity of fastenings of sandwich panels is presented. Additional information on the stiffness of fastenings at longitudinal joints of roof panels is given.
