What is the unique advantage of the Sigma section, compared with the C section?
Cold-formed steel (CFS) sigma sections differ from normal C sections in that they have two stiffeners in the web. They are currently extensively utilized in modern industrial buildings as purlins and side rails. The presence of web stiffeners in the sigma section moves the shear center closer to the section's C.G. and boosts resistance to web local buckling and distortional buckling. The behavior of the sigma section subjected to bending moment was compared to that of the C-Section in order to evaluate the viability of using sigma sections as an alternative to C-sections subjected to bending moment about the main axis. CUFSM was used to perform a finite strip analysis to determine the critical local, distortional, and lateral-torsional buckling moment of both the sigma and C-sections.
