The structure shown in figure is a $2-$D$,$ pin jointed truss supported on a pin at A and a roller at H $.$ The truss is

subject to ultimate limit state $($factored$)$ point loads. The self$-$weight of the truss is neglected. Determine the

adequacy of members AC and CE$.$ The members are A$36$ steel $(Fy=248$MPa,$Fu=400$MPa $)$ angle

sections with equal legs. Detail of joint $C$ is shown and assume edge distance to be $40$ mm $.$ Use standard hole

size and LRFD$.$

Given:

Bolt diameter $=16mm$
