“…Like for the more traditional hot-rolled carpentry components, imperfections can be found as out-ofstraightness of the member or as a distortion of the cross-section. An efficient set-up for the imperfection measurements has been proposed in literature [42] but, due to its complexity, it has not been used in the present research, as it happens for the commercial manufacturing tests. It is worth noting that initial geometric imperfections play a non-negligible role on the effective member performance when numerical finite element models are adopted.…”

Thin-walled cold-formed (TWCF) profiles are extensively used in adjustable selective pallet racks that represent the most common typology between the logistic solutions. In these structures, vertical members (uprights) are usually channels, often provided with intermediate stiffeners, rear flanges and additional lips. Furthermore, in order to allow for a rapid connection with beams and bracing components, usually uprights present regular perforation systems along their length. Nowadays, theoretical approaches available to design TWCF members are based on equations valid only for few unperforated (solid) cross-section geometries. As a consequence, rack manufacturing engineers frequently adopt the well-known design-assisted-by-testing approach to overcome this limitation and to assess accurately member performance. This approach, time consuming and cost demanding, stresses the need of further improvements required to cover aspects currently not considered in design codes.The paper summarizes the results of a study focused on the response of a commercial upright profile.In particular, 48 compression and 24 bending tests on perforated and unperforated profiles have been carried out. A summary of the experimental program is proposed together with the reelaboration of test data. Furthermore, the influence of perforation is discussed as well as key design geometric parameters. Finally, owing to the lack of information in major rack standard codes, three different proposals to evaluate the effective second moments of area have been developed, discussed and applied, hoping to contribute to standard improvements.

“…The steel storage racks compressive strength under applied axial forces has been studied (Elias et al 2018). Compared to numerical analysis, the results have shown the failure mode of global buckling as flexural and torsional.…”

Steel pallet racking industry has globally used from the industrial revolution and has deeply evolved from hot-rolled profile into cold-formed profile to raise the optimization in engineering field. Nowadays, some studies regarding cold-formed steel profile have been performed, but fewer studies in terms of cold-formed pallet racking specifically in connection due to the semi-rigid behavior by lug-hooked into the upright have been conducted. The objective of this study is to review the related literature on steel storage racking connection behavior.

“…There are numerous studies regarding industrial storage systems constructed of cold-formed steel. 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.…”

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.
