Torsion in thin-walled cold-formed steel beams

of thin-walled zee and sigma sections subject to a transverse load is studied analyti-cally and the results are compared with the experiments. A study on the flexural strength and deflections of discretely braced cold-formed steel channel and zee sections was conducted by Ellifrit et al. [10,14,22] at the Uni-versity of Florida.
