Punching of Chord Member due to Moment M_ip According to EN 1993-1-8, Table 7.5, Row 3.1

Punching the chord member due to the moment M_ip according to EN 1993-1-8, Table 7.5, row 3.1

M_{ip, i, Rd} = \frac{f_{y 0} \cdot t_{0} \cdot {d_{i}}^{2}}{\sqrt{3}} \cdot \frac{1 + 3 \cdot \sin (θ_{i})}{4 \cdot \sin^{2} (θ_{i})} / γ_{M 5}

M_ip,i,Rd	Design value of the moment resistance of the connection for bending in 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
y_M5	Partial safety factor
