Punching the chord member due to moment Mₒₚ according to EN 1993-1-8, Table 7.5, row 3.2

Punching the chord member due to moment M_op according to EN 1993-1-8, Table 7.5, row 3.2

M_{op, i, Rd} = \frac{f_{y 0} \cdot t_{0} \cdot {d_{i}}^{2}}{\sqrt{3}} \cdot \frac{3 + \sin (θ_{i})}{4 \cdot \sin^{2} (θ_{i})} / γ_{M 5}

M_op,i,Rd	Design value of moment resistance of connection for bending out of 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
y_M5	Partial safety factor
