Figure $4$ shows the beam and column that have to resist $300kN$ of shear action, using the bolt connection. By considering simple connections, prescribe and justify an appropriate configuration that can resist the shear action, predict possible failures that limit the design, and verify at least three design resistance. The design is limited to :

$($a$)$ Column size: $305305283$ UC$.$

$($b$)$ Beam size: $533210122$ UB$.$

$($c$)$ Both column and beam are made of $$275$ grade.

$($d$)$ The available size of the bolt is only MI $6$ of $4\mathrm{.}6$ bolt class.

$($e$)$ Provide sketching to illustrate the design.
