Given
L=5.9m = 5900 mm
Pu=2000$\times 10^{3}$N
required two channel back to back with battern & site welding $\gamma$ mw=1.5
2000$\times 10^{3}$=Area$\times$ 150
Area=13333.33mm$^{2}$
Area of each section=$\frac{13333.33}{2}=6666.67mm^{2}$
provide fcd=190mpa
Pu=Area$\times$ fcd
2000$\times 10^{3}=Area\times$190
Area=1056.31mm$^{2}$
Area of each section=$\frac{10526.31}{2}$=5263.15mm$^{2}$
2) Provide ISMC 350
Aprov=5366mm$^{2}$
$\gamma$ xx=136.6mm $ …
