Equivalent Net Cross-Section Area for Input in RF-/STEEL EC 3

N_{u, Rd} = \frac{0.9 \cdot A_{net} * \cdot f_{u}}{γ_{M 2}} \Rightarrow A_{net} * = \frac{A_{net, eff}}{0.9}

N_u,Rd	Design value of the tension resistance of the net cross-section
A_net,eff	Effective net cross-section area
A_net*	Equivalent net cross-section area for input in RF-/STEEL EC3
f_u	Tensile strength
γ_M2	Partial factor for cross-section resistance in case of failure due to tension
