Flange failure of chord member due to moment M_ip according to EN 1993-1-8, Table 7.5, row 1

M_{ip, i, Rd} = 4.85 \cdot \frac{f_{y 0} \cdot {t_{0}}^{2} \cdot d_{i}}{\sin (θ_{i})} \cdot \sqrt{γ} \cdot β \cdot k_{p} / γ_{M 5}

M_ip,i,Rd	Design value of moment resistance of connection for bending in plane of structural system for structural component i
f_y0	Yield strength of material of a chord member
t₀	Wall thickness of chord cross-section
d_i	Total diameter for CHS components i
θ_i	Enclosed angle between strut i and chord member
γ	Ratio of the chord member's width or diameter to the double of its wall thickness
β	Ratio of mean diameters or mean widths of strut and chord
k_p	Chord prestress coefficient
γ_M5	Partial safety factor
