Formula 2

However, analytical solutions for elastic distortional buckling indicate that, for most practical cases (for example, $L / h_{o}>10$ and $h_{o} / t_{w}<50$, where $L=$ length of span, $h_{o}=$ distance between flange centroids, and $t_{w}=$ thickness of web), the beam will be able to attain its plastic moment well before any global buckling occurs (Bradford and Gao, 1992).
