Q$(3)(35$ pt$)$

a$.$ Select an IPE tension member $5m$ long to resist a service dead load of $300kN$ and a

service live load of $700kN.$ Use S $235(F_y=235$MPa,$F_u=360$MPa$)$ steel. Assume that

the IPE member is connected using two lines of M$16($standard circular hole$)$ bolts at

each flange as shown in the figure. Use LRFD$.$ Take $U=0\mathrm{.}85.$

b$.$ Design the slip critical bolted connection shown in the figure to withstand the applied

loads. Used steel members are of class B faying surface, $=0\mathrm{.}40.$

Note: the number of lines shown in the figure is just an illustrative number. You have to

find the exact number of bolts and their layout. Take the thickness of the gusset plate

equal to the thickness of the flange of the IPE section.

c$.$ Check the block shear capacity of the connection.Q$(3)(35$pt$)$ a$.$ Select an IPE tension member $5$m long to resist a service dead load of $300$kN and a service live load of $700$kN $.$ Use S$235($F$\_($y$))=235$MPa,F$\_($u$)=(360$MPa$)$ steel.
