Formula 3

\begin{array}{l} W_{pl, y} = 2 \cdot (30 \cdot 2.5 \cdot 28.25 27 \cdot 1.3 \cdot 16) = 5, 360 {cm}^{3} \\ M_{pl, y, Rd} = W_{pl, y} \cdot \frac{f_{y}}{γ_{M 0}} = 5, 360 \cdot \frac{23.5}{1} = 125, 960 kNcm = 1, 259.6 kNm \\ A_{v, z} = A - 2 \cdot b \cdot t_{f} (t_{w} 2 \cdot r) \cdot t_{f} = 226 - 2 \cdot 30 \cdot 2.5 (1.3 2 \cdot 2.7) \cdot 2.5 = 92.75 {cm}^{2} \\ V_{pl, Rd} = A_{v, z} \cdot \frac{f_{y}}{\sqrt{3} \cdot γ_{M 0}} = 92.75 \cdot \frac{23.5}{\sqrt{3} \cdot 1} = 1, 258.41 kN \end{array}
