“…In a previous investigation by the authors (Casafont et al, 2012), it was demonstrated that k can be taken equal to 0 . 9 for a wide range of common rack columns (see the mentioned reference for the requirements to carry out the analysis with this k value).…”

“…The effect of holes can be directly taken into account in FEM models. It is not so easy to consider this effect when the two other methods mentioned are applied (see Casafont et al, 2012;Eccher et al, 2008;Moen and Schafer, 2009). This is the main reason why finite-element analyses have been extensively used in scientific investigations of members with perforations.…”

“…The next step was to verify whether the strength of the upright can be predicted from the reduced effective area determined in the distortional buckling test carried out at L SD-(ADþTF) : Some comments are included concerning the calculation performed with the European bucklingcurveforglobalbuckling(Equations1-4) (a) The reduced thickness approach is used to determine the properties of the cross-section for the calculation of flexural and torsional-flexural elastic buckling loads (see Casafont et al, 2012).

An investigation into the test method for distortional buckling of steel storage rack columns is presented. The main problem of the experimental method is to determine the length of the samples to be tested. The paper proposes to solve this problem by performing linear buckling analysis of the columns. Nowadays, linear buckling analysis can be easily carried out by practical designers with the help of newly developed programs based on the finite strip method and generalised beam theory. A simple test procedure is presented and validated in an experimental campaign on four different perforated rack columns. The tests also made it possible to observe the buckling behaviour of such columns, which involves a combination of different buckling modes.

“…This analysis takes into account the influence of the perforations by using an equivalent thickness for the distortional mode (t eq , Eq 2) on the web zone where the perforation is located. The mode used is based on [19] (Figure 19). …”
