A Comparative Analysis of Thin-Walled Sections Using Finite Element Modelling

Abstract

Thin-walled channel sections, such as Folded Sections, C-Sections, and Z-Sections, are extensively used in structural applications, particularly in civil engineering. This research investigates the behavior of cold-formed steel sections, including folded flanges, C-sections, and Z-sections, with respect to their ultimate load-carrying capacities. A numerical model will be developed using the finite element method in Abaqus software to simulate the behavior of these sections under axial compressive loading, covering both the elastic and plastic ranges. Comparative analysis of the folded sections, C-sections, and Z-sections is conducted. Z-section stands out with its significantly higher ultimate load capacity compared to the folded and C-sections. This can be attributed to its Z-shaped design. The objective of this study is to establish more robust design guidelines for the safe and efficient use of these sections in building structures. The findings will contribute to enhancing the reliability and economy of design practices for these structural elements.
