Equation of reduction factor on basis of linear M/N interaction

Equation of reduction factor on basis of linear M/N interaction
11-χ·λ¯2·χ·α+χ=1
χ Reduction factor from the ratio of the axial force at which the column fails due to flexural buckling and the plastic resistance
α The imperfection factor results from the ratio of the limiting slenderness to the imperfection amplitude.

Limiting slenderness
