ASSIGNMENT $2$

Given:

Imposed load on plan

$=0\mathrm{.}75k\frac{N}{m^2}$

$=0\mathrm{.}5k\frac{N}{m^2}$

$=5m.$

Dead load including selfweight of truss

Spacing between trusses

$=5m.$

Purlins are located on nodes.

All steel members are in grade $$275.$

e$).$ a$)$ Determine the point load, $P$

f$).$ Determine the maximum compression force in the top chord.

g$).$ c$)$ Determine the maximum tension force in the bottom chord.

$).$d$)$ Using d$$uble angles $2175506L,$ determine whether the angle section is suitable for the top chord.

i$).($C$)$ Using single angle $90908L,$ determine whether the angle is suitable for the bottom chord.

All members are connected at their ends with $2-$ M$20$ bolts in series.
