to back in opposite site of gusset plate 2)Angle place same side of gusset

Angle are tack bolted & provided wotj min of two bolts

Given P=178KN

l=3.05m

leff=0 8$\times$3.08

=2464mm

consider fed=150mpa

Pd=Ae$\times$fcd

178$\times10^{3}=Ae\times150$

back to back connection Ae=1186.67mm$^{2}$ Area required

Area of each angle=$\frac{1186.67}{2}$=56.33mm$^{2}$

Assume fcd=90mpa

Pd=Ae$\times$fcd

178$\times10^{3}$=Ae$\times$90 …
