Original Abstract

This paper deals with the problems of analysis and design of perforated thin-walled steel Sigma beams used in the storage systems and expedient flooring structures, in general. The verification of the torsion stiffness is a partial step to determine the ultimate and design strength of beams with respect to lateral torsion buckling. Both types of torsion stiffness (St. Venant and warping torsion stiffness) were examined. First the mathematical definitions for St. Venant torsion parameter It and warping constant Iw are being established. Then both torsion characteristics are verified by tests executed on three different lengths of beams (2, 3, 4 m).
