Fixings of sandwich panels in building applications

The paper introduces briefly the European Recommendations for Testing and Design of Fastenings of Sandwich Panels, written by the Joint Committee of ECCS TC7.9 and CIB W056. The Recommendations can be seen as an annex to the standard EN 14509 (2006), which concern the factory made sandwich panel products. The paper gives background information about the mechanical behavior and explains the effects of important parameters of a fastening loaded by tensile forces. A design formula is presented, which shows the influence of the essential mechanical parameters in the load-bearing capacity.
