Formulas: Transverse Stiffeners

Formula 1

(a) Transverse stiffeners are not required where $h / t_{w} \leq 2.54 \sqrt{E / F_{y}}$ , or where the available shear strength provided in accordance with Section G2.1 for $k_{y}=5.34$ is greater than the required shear strength.

h / t_{w} \leq 2.54 \sqrt{E / F_{y}}

Formula 2

\left(b / t\right)_{s t} \leq 0.56 \sqrt{\frac{E}{F_{y s t}}}

Formula 3

I_{s t} \geq I_{s t 2}+\left(I_{s t 1}-I_{s t 2}\right) \rho_{w}

Equation G2-19

\left.\frac{2.5}{(a / h)^{2}}-2\right\rvert\, b_{p} t_{w}^{3} \geq 0.5 b_{p} t_{w}^{3}
