For Class 1 classification, the following conditions must be met:

$\frac{b_{el}}{t} \leq \frac{145}{\sqrt{F_y}}$ for flange and $\frac{h}{t} \leq \frac{1100}{\sqrt{F_y}}$ for the web.

For Class 2 classification, the following conditions must be met:

$\frac{b_{el}}{t} \leq \frac{170}{\sqrt{F_y}}$ for flange and $\frac{h}{t} \leq \frac{1700}{\sqrt{F_y}}$ for the web.

For Class 3 classification, the following conditions must be met:

$\frac{b_{el}}{t} \leq \frac{200}{\sqrt{F_y}}$ for flange and $\frac{h}{t} \leq \frac{1900}{\sqrt{F_y}}$ for the web.

Flexural Member

Flexure

For laterally supported beams:

If class is 1 or 2: $M_{rx} = \phi ZF_y$

If class is 3: $M_{rx} = \phi S_xF_y$

The factored moment resistance is {{outputs.Mrx | katex}} $kN-m$

Shear

Factored Shear resistance $V_r = \phi A_wF_s$ , where:

$A_w = d * w$

$F_s = 0.66F_y$ when $\frac{h}{w} \leq \frac{1014}{\sqrt{F_y}}$

$F_s = \frac{670\sqrt{F_y}}{\frac{h}{w}}$ when $\frac{1014}{\sqrt{F_y}} \lt \frac{h}{w} \leq \frac{1435}{\sqrt{F_y}}$

$F_s = \frac{961200}{(\frac{h}{w})^2}$ when $\frac{h}{w} > \frac{1435}{\sqrt{F_y}}$

The shear resistance for web is {{outputs.SR | katex}} $kN$
