Formula 1

Flexural-torsional buckling need not be considered when b/t≤0.71E/Fyb / t \leq 0.71 \sqrt{E / F_{y}}.

b/t≤0.71E/Fyb / t \leq 0.71 \sqrt{E / F_{y}}

Equation E5-1

Lcr=72+0.75Lra\frac{L_{c}}{r}=72+0.75 \frac{L}{r_{a}}

Formula 3

(i) When Lra≤75\frac{L}{r_{a}} \leq 75

Lra≤75\frac{L}{r_{a}} \leq 75

Equation E5-3

Lcr=60+0.8Lra\frac{L_{c}}{r}=60+0.8 \frac{L}{r_{a}}

Formula 5

(ii) When Lra>75\frac{L}{r_{a}}>75

Lra>75\frac{L}{r_{a}}>75

Equation E5-4

Lcr=45+Lra\frac{L_{c}}{r}=45+\frac{L}{r_{a}}
