“…These elements are taken from a real storage system partially destroyed because of the accumulated damage created by the light impacts with the forklifts operating in the magazine area. It is the continuation of work presented on XXII, XXIII and XXIV LSCE conferences: thin-walled bars theory [2][3][4][5][6] calculations as well as finite element method modelling [4,[7][8][9][10] were presented in paper [11], elastic buckling modes were analysed in paper [12] and experimental results can be found in paper [13]. Some very early experiments and calculations were also presented in paper [14].…”

“…A non-negligible advantage of the general meth-od with respect to the other two alternatives consists in the fact that only FE numerical analyses and/or analytical computations are required, avoiding hence stub column and beam tests. Despite very refined FE beam formulations that are nowadays available to model cold-formed thin walled members [34][35][36][37][38][39][40][41][42][43][44][45], the buckling analysis of the perforated beam-columns can be carried out via commercial (and economical) finite element analysis programs to model the uprights by means of elastic shell elements: in this way the influence of the perforation sys-tems reflects directly on the critical load multiplier α cr,op . Moreover, also the term α ult,k , which is related to the attainment of the yielding of the most stressed point of the net crosssection under axial load and bending moment, can be estimated directly.…”

“…The introduction of perforations in buckling mode identification, GBT linear and eigenbuckling analysis has also been studied. Nedelcu [23] presented a methodology based on GBT capable of identifying the modal participation of pure deformation modes in a shell finite element analysis of perforated thin-walled members. Casafont et al [24] used constraint equations to link the degrees of freedom of perforated and non-perforated beam longitudinal elements in a linear buckling analysis.…”
