Adjusted Reduction Factor According to Annex E for Cross-Section Parts Supported on Two Sides

(a) for cross - section parts supported on two sides :

ρ = \frac{1 - 0.055 \cdot \frac{(3 + ψ)}{{\bar{λ}}_{p, red}}}{{\bar{λ}}_{p, red}} + 0, 18 \cdot \frac{({\bar{λ}}_{p} - {\bar{λ}}_{p, red})}{({\bar{λ}}_{p} - 0.6)} \leq 1.0

(b) for cross - section parts under compression supported on one side :

ρ = \frac{1 - \frac{0.188}{{\bar{λ}}_{p, red}}}{{\bar{λ}}_{p, red}} + 0, 18 \cdot \frac{({\bar{λ}}_{p} - {\bar{λ}}_{p, red})}{({\bar{λ}}_{p} - 0.6)} \leq 1.0
