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}
