Formula 4

\begin{array}{l} τ_{| |, Vz, i} = \frac{- V_{z} \cdot S_{y, i}}{I_{y} \cdot {Σa}_{w, i}} \leq \frac{f_{u}}{\sqrt{3} \cdot β_{w} \cdot γ_{M 2}} = \frac{36.0}{\sqrt{3} \cdot 0.8 \cdot 1.25} = 20.78 kN / cm ² \\ τ_{| |, Vz, 1} = \frac{- 350 \cdot 1, 175}{71, 095 \cdot 2 \cdot 0.4} = - 7.23 kN / cm ² < 20.78 kN / cm ² \\ τ_{| |, Vz, 2} = \frac{- 350 \cdot 1, 700}{71, 095 \cdot 2 \cdot 0.5} = - 8.37 kN / cm ² < 20.78 kN / cm ² \\ τ_{| |, Vz, 3} = \frac{- 350 \cdot 1, 322}{71, 095 \cdot 2 \cdot 0.4} = - 8.13 kN / cm ² < 20.78 kN / cm ² \end{array}
