Description
Summary:Present paper presents the experimental and numerical approach for determining the axial strength of cold formed pallet rack uprights sections with and without perforations in accordance to European design code. The study presented hereafter is part of an extended experimental and numerical study carried out within the CEMSIG Research Centre (http://cemsig.ct.upt.ro), dep. of Steel Structures and Structural mechanics, POLITEHNICA University of Timisoara. Furthermore, as observed by many researchers, the influence of end restraints, particularly warping, is of paramount importance when discussing about distortional buckling. Using calibrated and validate finite element models, a numerical study was conducted to determine the influence of end restraints, warping in particular, on perforated and unperforated pallet rack uprights sensitive to distortional buckling. The simulations have been conducted on a pallet rack upright section sensitive to distortional buckling, considering short (distortional buckling length range) and long specimens (interactive distortional - global buckling range).
