Inserting Moment Equation Depending on Elastic Buckling Load in Interaction Formula

Entering the moment equation into the linear interaction

\frac{\frac{1}{1 - \frac{N}{N_{cr}}} \cdot N \cdot e_{0}}{N_{pl} \cdot \frac{h}{2}} + \frac{N}{N_{pl}} = \frac{1}{1 - \frac{N}{N_{cr}}} \cdot \frac{N}{N_{pl}} \cdot \frac{e_{0}}{\frac{h}{2}} + \frac{N}{N_{pl}} = 1

N	Maximum axial force before buckling
e₀	Selected pre-deformation
N_cr	Critical buckling load
N_pl	Plastic resistance to axial forces
h	Cross-section depth
