“…Consequently, the curves obtained with these analyses are more similar to the experimental ones. (2) After that, Equation 3 validates the load case of a rack column under compression and bending load provided by the EN15512 (part 9.7.6.4) is used. Where the parameter K LT can be obtained by Eq (4)…”

“…Extensive research has been focused on members loaded under pure compression; among these, [2][3] that are devoted to experimental testing of compressed members. Three methods (analytical, experimental and FEA) to estimate the effective area and the position of the centre of gravity for perforated sections are presented in [2].…”

“…Three methods (analytical, experimental and FEA) to estimate the effective area and the position of the centre of gravity for perforated sections are presented in [2]. Experimental deformations were measured on specimen lengths prone to distortional buckling failure in order to analyse the interaction between distortional and global buckling modes [3].…”

“…The local-distortional buckling interaction in fixed-end CFS uprights was experimentally assessed by Pedro et al [12]. In another project, local-distortional buckling interaction of short upright columns was studied by Roure et al [13] through the concept of reduced thickness of the stiffeners. They reported that the current design codes are not accurate and the effect of buckling interaction needs to be also considered.…”

Investigation of a Method for Strengthening Perforated Cold-Formed Steel Profiles under Compression Loads

Cold-formed steel (CFS) storage rack structures are extensively used in various industries to store products in safe and secure warehouses before distribution to the market. Thin-walled open profiles that are typically used in storage rack structures are prone to loss of stability due to different buckling modes such as local, distortional, torsional and flexural, or any interaction between these modes. In this paper, an efficient way of increasing ultimate capacity of upright frames under compression load is proposed using bolts and spacers which are added externally to the section with certain pitches along the height. Hereinto, experimental tests on 81 upright frames with different thicknesses and different heights were conducted, and the effect of employing reinforcement strategies was examined through the failure mode and ultimate load results. Non-linear finite element analyses were also performed to investigate the effect of different reinforcement spacing on the upright performance. The results showed that the reinforcement method could restrain upright flange and consequently increase the distortional strength of the upright profiles. This method can also be effective for any other light gauged steel open section with perforation. It was also observed that the reinforcement approach is much more useful for short length upright frames compared to the taller frames.

“…Plates are clamped to the end section and restrain the local distortion of the section as shown in Figure 12. The details of such testing are spelled out in [9,10]. Table 1 shows the experimental results for all tested lengths.…”

The first step of this investigation has been to analyze the cold roll forming process of the upright, using a specific finite element (FE) program that includes geometric and material non-linearity. After the process simulation, the residual strains and stresses are obtained. In a second step, these values are introduced as initial stress state in the FE model that will be used to analyse the behaviour of the upright column under compression. The compression analysis is also completed with geometric and material non linearity, so that elastic and inelastic buckling can be modelled, and the ultimate loads are obtained. The results are compared with the ones obtained by the classic two step method (linear elastic buckling to obtain an initial deformation shape and then use it as initial geometric imperfection for the nonlinear analysis). They are also compared to the results obtained experimentally.
