“…Camotim et al [27] presented the general beam theory (GBT) formulation, and corresponding finite element implementation to analyse local and global buckling behaviour of thin-walled members with arbitrary loading and support conditions. Macdonald et al [28] described the main types of cold-formed steel members and discussed the particular characteristics affecting their design. The buckling problem of flanges of cold-formed thin-walled beams is closely connected with shapes of cross section profiles of these flanges.…”

This paper presents the experimental investigation conducted on cold formed steel built up box shaped beams strengthened using CFRP. Box shaped cross sections were made of connecting two channel members using screws. The selected beam specimens were 300mm, 400mm and 500mm in length with screw spacing of 100mm and edge distance of 50mm. Firstly, Single point load bending test were carried out to determine the maximum load, deflection and failure modes for plain sections. Secondly, same bending test were repeated for CFRP wrapped sections to determine the maximum load, deflection and failure mode. The maximum load capacities calculated using AISI specifications are compared with experimental maximum loads which are in good agreement.

A series of axial compression tests was conducted to investigate the compressive behaviour of cold-formed steel stub columns with relatively thick walls (6mm and 10mm, respectively). Four different inner-stiffener arrangements were considered.Tensile coupons were cut from different parts of the square hollow section (SHS) sections to obtain a full picture of the enhanced material properties due to the cold-forming process. A finite element model was also developed and employed to provide a numerical perspective of the behaviour of the SHS columns. The applicability of two code-specified methods for the calculation of the strength of thin-walled cold-formed SHS columns for the present thick-walled cases is examined. The comparison shows that the AISI (and similarly AS/NZS) method tends to overestimate the sectional strength for the unstiffened and partially stiffened 6-mm thick columns, but predicts generally well (with slight underestimate) in the cases of well-stiffened 6-mm columns and all the 10-mm thick columns. The GB method, on the other hand, appears to predict well for all cases where the stiffening effect was less significant, but underestimates the sectional strength in the well-stiffened cases.
