Abstract
Although the hot-rolled steel members have been considered as the most common and widely used steel profiles, but light gauge steel (LGS) use in structures is widely increasing recently. The structural attitude of this light gauge is characterized by different buckling modes as local, distortional, and torsional buckling. Light gauge steel sections are being produced in many forms. One of these forms is the hollow flanged beam sections which proved its effectiveness but their behavior still not fully understood. In this paper, the moment behavior of LGS beams is verified using the finite element analysis. A numerical study was applied to figure out the parameters affecting the behavior of the LGS beams in case of using hollow flanges, either rectangular or triangular, with and without vertical stiffening under flexural loading. All beams were simply supported and subjected to two-point loadings configuration. The ultimate load capacity and failure mode of all beams were determined. Three different design codes were utilized to validate the results.
