Shear in Mortise and Tenon connection

[Robbiee]

Hello,
I am reviewing an existing old structure, of which most joints are mortise and tenon. Please see attached sketch.
my question is: do you take the shear resistance at the face of the column where the section of the beam is reduce or at d distance from the face of the column. I should note that the joints don't have shoulder. Thanks for the help.

Not at d away.

Agree... at the reduced section as it enters the column.

We normally provide a shoulder in the column for the beam to bear on, however, per your attached figure, use the reduced section.

Thanks all for the replies.

Picked this up on DesignToEurocodes website... (en Francais), but can work your way through it...
