Flexural-Torsional Buckling Analysis of Steel Beams under Transverse Loads in High Temperature

Abstract:

Flexural-torsional buckling of steel beams in high temperature is studied by adopting the method of theoretical analysis. The flexural-torsional buckling critical moment equations of steel beams under concentrated transverse loads are driven in high temperature ranging from 20°C to 300°C. In order to verify the validity of the theoretical analysis equations, a steel beam model under concentrated transverse load is designed. The flexural-torsional buckling critical moments and critical stresses are calculated under different temperature conditions. The influence of load point on flexural-torsional buckling critical moment and critical stress are obtained. The variation tendency of flexural-torsional buckling critical moment and critical stress against temperature are also presented.
