Flange failure according to EN 1993-1-8, Table 7.2, row 3.2

N_{1, Rd} = \frac{k_{g} \cdot k_{p} \cdot f_{y 0} \cdot {t_{0}}^{2}}{\sin (θ_{1})} \cdot (1.8 + 10.2 \cdot \frac{d_{1}}{d_{0}}) / γ_{M 5}

N_{2, Rd} = \frac{\sin (θ_{1})}{\sin (θ_{2})} \cdot N_{1, Rd}

N_1,Rd	Design value of axial force resistance of connection for strut 1
k_g	Factor for nodal connections with a gap g
k_p	Chord prestress coefficient
f_y0	Yield strength of material of a chord member
t₀	Wall thickness of chord cross-section
θ₁	Enclosed angle between strut 1 and chord member
d₁	Total diameter of strut 1
d₀	Total diameter of chord member
y_M5	Partial safety factor
N_2,Rd	Design value of axial force resistance of connection for strut 2
θ₂	Enclosed angle between strut 2 and chord member
