A double $-$channel shape, $2Cg20,$ is used as a tension member. The channels are bolted to $12mm$ thick gusset plate with $22mm$ bolts. The tension member is $A572$ steel $(F_y=345$MPa and $F_u=450$MPa $)$ and the gusset plate is A$36$ steel and $\{$:$F_u=400$MPa$).$ Use LRFD and consider all limit states including block shear strength.

Compute the design strength $(KN)$ based on yielding. $0$

Compute the nominal strength $(KN)$ based on fracture. $0$

Compute the design strength $(KN)$ of the channel based on block shear. $0$

How much factored tensile load $($KN$)$ can be applied?$0$
