Reduced slenderness ratio based on the applied compressive stress

{\bar{λ}}_{p, red} = {\bar{λ}}_{p} \cdot \sqrt{\frac{σ_{com, Ed}}{\frac{f_{y}}{γ_{M 0}}}}

λ_{p, red}	Reduced slenderness ratio
λ_p	Buckling slenderness
σ_{com, Ed}	Design value of the compressive stress
f_y	Yield strength
γ_M0	Partial safety factor for cross -section resistance
