Formulas: Flange Local Buckling of Tees and Double-Angle Legs

Equation F9-15

where

$\begin{aligned} S_{x c} & =\text { elastic section modulus referred to the compression flange, in. }^{3}\left(\mathrm{~mm}^{3}\right) \\ \lambda & =\frac{b_{f}}{2 t_{f}}\end{aligned}$

$\lambda_{p f}=\lambda_{p}$, the limiting width-to-thickness ratio for a compact flange as defined in Table B4.1b

$\lambda_{r f}=\lambda_{r}$, the limiting width-to-thickness ratio for a noncompact flange as defined in Table B4.1b

Formula 2

$\lambda_{p f}=\lambda_{p}$, the limiting width-to-thickness ratio for a compact flange as defined in Table B4.1b
