Q$1($a$)$ A single angle tie member $($Fig$.$ Q$1)$ to transmit the axial tension of $500$

$kN,$ with four M$16$ grade S$275$ bolted connections. Given the unequal

angle $125758L$ with longer leg connected to $12mm$ thick gusset

plate, determine the tension capacity of the system and justify the

adequacy of section.

$($b$)$ Proposed a new section of tension member in $($a$)$ if the section is

inadequate.

Q$2$ Design a compression member using $2$ angles for a factored load of $300kN.$

Center to center length of member is $3m.$ Use S$275$ grade steel. Design welded

connection.
