Item Flexural behavior of cold-formed steel beams : development of generalized direct strength method and efficient built-up sections for local buckling(Université Badji Mokhtar Annaba, 2024) MAIZI, Salah-EddineThis thesis investigates the flexural behavior of innovative cold-formed steel (CFS) built-up closed sections, focusing on cross-sectional buckling failure. A Finite Element (FE) model is developed and extensively validated against various built-up closed and open sections in bending. Three parametric studies are conducted, each exploring different aspects of the proposed built-up closed sections.
