Stability of Thin-Walled Beams with Lateral Continuous Restraint

Abstract

Metal beams of thin-walled cross-sections have been widely used in building industry as members of load-bearing structures. Their resistance is usually limited by lateral torsional buckling. It can be increased in case a beam is laterally supported by members of cladding or ceiling construction. The paper deals with possibilities of determination of critical load of thin-walled beams with lateral continuous restraint which is crucial for beam buckling resistance assessment.

Numerical Static Analysis of the Curtain Wall with Light Steel Structure

“…The analyses presented in the study show that it is useful to verify the information contained in the manufacturer's documents. The FEM method can be employed in the analysis of thin-wall profiles to verify calculations [10] and assumptions of the study for the adopted model [11,12].…”

The Problem of Consideration Torsion Emergence in Beams

“…Modern theoretical and experimental-theoretical studies of the stress-strain state and stability of thin-walled steel beams, without restraining and restrained, are presented in [1,2,3] and other researchers. Among the main sources, where the results of beam torsion and stability research are noted, the works of the German classical technical school representatives are included [4,5,6].…”
