  • Abstract:
  • Built up steel beams composed of cold-formed sections are increasingly used in buildings because of their lightness and ability to support large spans. Cold-formed Steel members have thinner elements, resulting in peculiar failure modes such as local and distortional buckling, which are not common in hot rolled members. Therefore, detailed study was focused into local buckling behaviour of cold formed steel beams composed of four channel sections connected by self-driving screws at flanges. In this thesis, the numerical procedure was developed using ABAQUS software and verified by validating the paper “Behaviour and design of cold-formed steel built-up I-beams composed of four channels” D. Amali (2024). The dimensions of the specimens were selected based on Eurocode Specifications (EN 1993-1-3(2006)). The parametric study was conducted by using the validated numerical model for 15 cross sections. All the parametric model were analyzed for four points bending under simply supported condition. The sectional dimensions were varied based on four different aspect ratios and analyzed with three different yield stresses such as 250,350 and 450 MPa using ABAQUS software.
