Tutorial # $2$

Check the adequacy of a diagonal truss in carrying a nominal tensile load of $715$ kN $($Analysis was on basis of dead load only$).$ The member is made of steel of Grade S$355$JR$.$ Initially the member consisted of a $120$ X $12010$ angle on the outside only, and later it was reinforced with a $1205513$ channel on the inside. The two sections are connected by a single row of M$24$ bolts in the centre of the sections and spaced at $65$ mm centre to centre. The end distance is $60$ mm as depicted in Diagram Q$1.$ The holes in the members are punched.
