Original Abstract

Sandwich panels have been used in building industry as roof and wall cladding. Usually they are supported by cold-formed steel members (purlins, girts). Restraint given to a thin-walled member by sandwich panels prevents its deformation and positively influences its buckling resistance. In case of sandwich panels, it is possible to utilize their shear stiffness to stabilize a cold-formed member against lateral displacement under downward as well as uplift load acting on sandwich panels. Torsional restraint can be standardly considered for downward load only. In some applications with cold-formed sections certain value of torsional restraint under uplift load can be considered. Determination of this value should be assisted by testing.
