Originální abstrakt
This paper deals with the problems of analysis and design of thin-walled steel beams with circular web holes. The analysis based on the finite element method modeling is being performed on the case of perforated Sigma beams used in the storage systems and expedient flooring structures. The Sigma beams are generally used as 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 the results of FEM analysis are compared with the bending resistances calculated according the Eurocode design procedure.
