$1$ Determine the design strength for the two ISA sections connected on either side of a $20mm$ gusset

plate by a line of $20mm$ dia bolts placed at $50mm\frac{c}{c}$ distance with $40mm$ end distance. For the ISA

section and no$.$ of bolts, refer Table $1.$

Also check whether the bolt arrangement is sufficient to take the load.

Assume bolts of grade $4\mathrm{.}6,$ and rolled sections and gusset plates are Fe$410$W$.$

W$=100$

t$=6$
