Equation 6.2: Linear Interaction of Axial Force and Moment Loading

Linear interaction of axial force and moment loading according to EN 1993 1-1

\frac{N_{E d}}{N_{R d}} + \frac{M_{y, E d}}{M_{y, R d}} + \frac{M_{z, E d}}{M_{z, R d}} \leq 1

N_Ed	Design value of the existing axial force
N_Rd	Design value of the allowable axial force
M_y,Ed	Design value of the existing bending moment about the local y-axis
M_{y, Rd}	Design value of the allowable bending moment about the local y-axis
M_z,Ed	Design value of the existing bending moment about the local z-axis
M_{z, Rd}	Design value of the allowable bending moment about the local z-axis
