“…NBR 15524 (ABNT NBR 15524-2:2007, 2007) provides two possibilities to consider the effects of distortional buckling: using experimental tests or numerical analysis. To evaluate the distortional buckling, a finite element analysis using the calibrated numerical model of Neiva et al (Neiva et al, 2018) via software ANSYS (ANSYS Inc, 2012) was performed. NBR 15524 (ABNT NBR 15524-2:2007, 2007) evaluates the distortional buckling influence by considering a column length closest to one meter (1 m), therefore, in order to accommodate the perforations and guarantees the normative prescriptions, the column length of 960 mm was chosen.…”

“…Global buckling is characterized by instability due to lateral displacements along the element length due to flexural, torsional, or flexural-torsional buckling. More information on the instability modes can be found at (Bonada et al, 2015;C D Moen & Schafer, 2011;Neiva, Sarmanho, Faria, Souza, & Starlino, 2018;Pastor et al, 2013;Ribeiro, 2006;Silva, L.

“…The main elements are studied separately, including continuous perforated uprights, beams, and connections (Baldassino, Bernuzzi, & Simoncelli, 2019;Bernuzzi & Simoncelli, 2017;Elias, Neiva, Sarmanho, Alves, & Castro, 2018;Huang, Wang, Zhao, & Sivakumaran, 2021;Liu, Pekoz, Gao, Ziemian, & Crews, 2021;Neiva et al, 2018;Pierin & Pignatta, 2015;Prabha, Marimuthu, Saravanan, & Arul Jayachandran, 2010;Sena Cardoso & Rasmussen, 2016). Neiva et al (Neiva et al, 2018) carried out a numerical and experimental study about uprights with perforated section racktype in a cold-formed profile. Axial compression tests were performed, and a numerical model with material and geometric nonlinearities was calibrated.…”

Brazilian standards for design of cold-formed steel (ABNT NBR 14762:2010, 2010) and design of pallet racks (ABNT NBR 15524-2:2007, 2007) have different procedures to determine the strength of columns under axial compression, using different buckling curves. This paper aims to evaluate the efficiency of using cold-formed Brazilian standard buckling design curve instead of the formulations of the pallet-rack design standard to study the use viability of the equations in the calculation procedure for computing the uprights compressive strength. This strength was calculated in four ways: one using the original equations of pallet-rack Brazilian standard, and the other three using adaptations of the buckling curve from the cold-formed steel design standard. A theoretical and numerical procedure based on finite element analysis concerning local, global, and distortional buckling and imperfections was performed. Furthermore, experimental results were also consulted to determine the effective area of studied cross-sections considering the effects of local buckling and the presence of continuous perforations. The results show that the proposed modifications are consistently correlated to the results obtained using the original equations of ABNT NBR 15524, indicating the viability of using the buckling curve of ABNT NBR 14762.

“…The authors concluded that parameters such the height of the pallet beam, the column's thickness and the connector's geometry affects the strength and stiffness of the connector. Several numerical and experimental studies [3][4][5] have been carried out to investigate the influence of perforations on the upright's stability and load capacity. Bajoria and Talikoti [6] determined the flexibility of beam-to-column connectors used in thin-walled cold-formed steel pallet racking systems by two different ways.…”

This study presents an experimental and numerical research into the behavior of beam-to-upright end connections, which are part of steel storage systems. A total of 21 cantilever tests comprising three upright and four beam cross sections, were conducted, and a finite element numerical model was developed. The mod el was developed to compare its results with experimental results and to extrapolate these results in a parametric analysis. The aim of the study is to evaluate the behavior, semi-rigidity, and influence of the geometric parameters in the stiffness of beam-upright lipped connections of pallet-type industrial storage systems. The results of the numerical model showed good correlation with the experimental results, in terms of moment-rotation behavior and the initial stiffness values, with a maximum differenc e of 10%. In the parametric analysis, a pattern was observed in the variation of stiffness when the dimensions-mainly the height of beams-of the prototypes were increased.
