Detemine factor Udl on laterally unsupported beam ISLB 300 of span 3.25m s.s at the ends

Given ISLB 300

D=300 bw=150 tf=9.4

tw=6.7 $\gamma_{1}$=15

Ze=488.9$\times 10^{3}$

Iz=7332.9$\times 10^{4}mm^{4}$

Iy=376.2$\times 10^{4}mm^{4}$

Zp=554.32$\times 10^{3}mm^{4}$-- Is code

span length =3250mm

d=300-2$\times9.4-2\times 15$=251.2

1) sectional classification

$\frac{b}{tf}=\frac{bf/2}{tf}=7.98 \lt$ 9.4 $\epsilon$

$\frac{d}{tw}=\frac{D-2tf-2R_{1}}{6.7}=\frac{251.2}{6.7}=37.49\lt 84 \epsilon$
