Originální abstrakt

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 Sigma beams are generally use as a floor girders which are subjected to the bending. In some cases the beams are not laterally restraint and the effect of lateral torsional buckling may occur. In the current engineering practice several design procedures are used to determine the bending resistance with respect to lateral torsional buckling. In this paper two of the procedures, which are commonly used in the practice, are described and their results are mutually compared. The design bending resistances calculated according to both methods are experimentally verified on the case of simply supported beam loaded with two concentrated loads in thirds of the span.
