Torsion in thin-walled cold-formed steel beams - ScienceDirect

The nonlinear biaxial bending behavior of thin-walled zee and sigma sections subject to a transverse load is studied analytically 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 University of Florida.

Thin-walled profiles in combination with good mechanical properties of steel leads to reduction of weight and lower price on these structures [3] , [4]. However, there are some disadvantages too. The designing of thin-walled profiles can be problematic due to complicated design methods [5] , [6]. Also the important factors are loosing of stability of an element or buckling [7].
