Abstract EN
Numerical analyses and theoretic analyses are presented to study the elastic buckling of H-section beam web under combined bending and shear force.
Results show that the buckling stress of a single web with clamped edges gives a good agreement with the buckling stress of an H-section beam web when the local buckling of the beam is dominated by the web buckling.
Based on theoretic analyses, a parametric study is conducted to simplify the calculation of buckling coefficients.
The parameters involved are clarified first, and the improved equations for the buckling coefficient and buckling stress are suggested.
By applying the proposed method, the web buckling slenderness ratio is defined.
It is verified that the web buckling slenderness ratio has a strong correlation with the normalized ultimate strength of H-section beams when the buckling of the beams is dominated by web buckling.
Finally, a design equation is proposed for the ultimate strength of H-section beams.
