ABSTRACT

The present research focuses on investigating the behavior of cold-formed steel (CFS) canal sections with back-to-back built-up members subjected to flexure, including the capacity, maximum load, load-deflection curve, and buckling failure. In the analytical studies outlined in Indonesian Standard SNI 7971:2013, which is referenced in AS/NZS 4600:2005, the final result will be evaluated compared to a single canal section through numerical analysis with ABAQUS. This member, made from double canal type C80x30x0.75, was tested on strong axes. A shell element with G550 characteristics formed the beam. It was characterized as utilizing the S4R shell element, which provides a node with six degrees of freedom. The CFS profile was measured at 80 mm height, 30 mm width, and 9 mm lip depth, with a three-point bending load applied to a 240 mm long beam and 150 mm space between bolt- connections. The analysis stated that the flexural capacity from both numerical and analytical studies had similar results. It reveals that the lip section experiences the highest stress. Applied double-canal back-to-back built-up section members increased the maximum load capacity by decreasing the number of deflections. The beam experiences local buckling failure in the middle span below the external load, possibly due to the profile's too thin thickness. Despite the inconsistencies in the ABAQUS analysis due to local buckling in the supports, stiffeners are necessary to increase load retention and minimize local buckling. We need more research to investigate how screw spacing affects beam structure capacity and how to apply stiffeners to cold-formed steel beam elements.
