A single $C25037$ tension member made of $350W$ steel is bolted to a gusset plate, as shown

in the figure below. The bolts are installed in pairs at a longitudinal spacing of $60mm,$ as

indicated, but the total number of bolts is as yet unknown. Bolts will be used $($and confirmed

on site$)$ that result in the threads being excluded from the shear plane. Determine the total

number of A$325$ M$20$ bolts that are required to develop the factored tensile capacity of the

channel member, considering both member and connection checks. You may assume that the

gusset plate is adequate in all respects. Summarise your design by making a neat sketch of

the connection $($do not use the figure provided for your summary sketch$).$ Hint: Complete the

design neglecting block shear and then confirm that the joint will not fail in this mode $($if it

does, you'll need to lengthen the connection accordingly$).$

Note: Topics $03$ and $04$ are very closely linked. You will need to look at the Tension Member

Connections notes up to page $6$ to complete all parts of this question.
