![]() ![]() The ultimate load has also been calculated according to the European Standards and compared to experimental results. Experimental tests have been performed reproducing the load conditions in order to validate the FEA results. The influence of bending on the strength capacity of rack uprights is analysed through finite element analysis, where residual stresses and strength enhancement induced during cold forming of sections are also considered. ![]() Bending is induced by means of axial forces eccentrically applied. The main objective of this paper is to analyse the influence of the bending moment on the load bearing capacity of rack uprights subject to axial load together with bending moment. Therefore, the uprights are thin-walled singly symmetrical perforated open cross-sections bearing axial load and bending moment simultaneously. The loads acting on the structure are induced by the weight of pallets to be stored, and transmitted to the uprights by the semi-rigid connection system. The complexity of these components, with local, distortional and torsional/flexural buckling behaviour, represents a challenge in structural design. For this reason, the uprights contain holes and perforations distributed along their length. ![]() The beam-upright connections are normally clipped in order to select the beam levels required and for ease of assembly. A pallet rack is a structure in which the beams and uprights are cold-formed steel sections. A truck driver and his job colleagues figures out how to make the smart move, on their many trips to Finland: Tinkering with cargo pallets that can be sold. ![]()
