Abstract

The paper summarizes the results of experimental and numerical investigations, carried out at the CEMSIG Research Center ( <ext-link ext-link-type="uri" xlink:href="http://cemsig.ct.upt.ro">http://cemsig.ct.upt.ro</ext-link> ) of ‘Politehnica’ University of Timisoara, on compression members of pallet racks. Members of two different cross-sections, with and without perforations, have been tested on the aim to calibrate a design approach to evaluate their ultimate strength and, on this basis, to check the buckling resistance of bar members accounting for distortional-global interaction. The lengths of upright specimens and testing procedure, for local and distortional buckling, were chosen according to European pallet rack design code provisions. Test on base materials and imperfection measurements have been also performed. In order to study the distortional-global interactive buckling, the ECBL method has been used. The paper presents the main results of these investigations.
