The billboard post support a 5KN dead load as shown. The cantilever beam and the brace is pinned connected to the post. Assume that the connections along the cap and the cap plate is adequate, as well as the gusset plate and the cap plate. Use LRFD design considerations. a.) Determine the ultimate tensile force the brace carries. b.) Determine the adequacy of Connection 1 the bolt where 2- 16mm Ø A325 hex bolt and the plates where A36 steel. c.) If the connection at Connection 1 will be a welded connection what will be the adequate thickness of the weld. Note that the welds are only applied at the sides of the cap plate. Use electrode 70 for the weld. d.) Determine the adequacy of the connection due to shear and tension in Connection 2 if the bolts were 4- 12mm Ø A325 hex bolt.

Question
The billboard post support a 5KN dead load as shown. The cantilever beam and the brace is pinned
connected to the post. Assume that the connections along the cap and the cap plate is adequate, as well as
the gusset plate and the cap plate. Use LRFD design considerations.
a.) Determine the ultimate tensile force the brace carries.
b.) Determine the adequacy of Connection 1 the bolt where 2- 16mm Ø A325 hex bolt and the plates
where A36 steel.
c.) If the connection at Connection 1 will be a welded connection what will be the adequate thickness of
the weld. Note that the welds are only applied at the sides of the cap plate. Use electrode 70 for the
weld.
d.) Determine the adequacy of the connection due to shear and tension in Connection 2 if the bolts were
4- 12mm Ø A325 hex bolt.
