COLUMN - BEAM JOINT DESIGN RCDC

Hello i would like to know what needs to be considered in order to ensure beam - column joint is stronger, especially when the beam width is greater than column width,lets assume my beam is 400mm x 600mm while column is 250mm × 300mm.

Is there any special detailing needs to be considered with this kind of geometry?

Can RCDC design this kind of joint using BS 8110?
