Flange Failure of Chord Member due to Moment Mₒₚ According to EN 1993-1-8, Table 7.5, Row 2

Flange failure of a chord member due to the moment M_op according to EN 1993-1-8, Table 7.5, Row 2

M_{op, i, Rd} = \frac{f_{y 0} \cdot {t_{0}}^{2} \cdot d_{i}}{\sin (θ_{i})} \cdot \frac{2.7}{1 - 0.81 \cdot β} \cdot k_{p} / γ_{M 5}

M_op,i,Rd	Design value of the moment resistance of the connection for bending out of plane of the structural system for the structural component i
f_y0	Yield strength of material of the chord member
t₀	Wall thickness of the chord cross-section
d_i	Total diameter for CHS components i
θ_i	Enclosed angle between the strut i and the chord member
β	Ratio of mean diameters or mean widths of the strut and the chord
k_p	Chord prestress coefficient
y_M5	Partial safety factor
