How to determine if a joint can be considered embedded
How to determine if a joint can be considered embedded
(OP)
We plan on adding a cantilever slab onto a wall, and I'm the sure the joint can be considered as an embedded joint. I couldn't find anything in the national standards guides (CSA).
See picture for planned slab details. Please not the the angles at the right of the pictures are simply guides for the underlying brick wall.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

What I'm wondering is if the scenario works at all, as in, can it be considered Diagram A, or is it Diagram B because rebars and a straight joint are not enough for the slab to be considered embedded.

However, from the picture you provided it appears that the slab has vertical supports on both ends? This would be a much simpler design.

>so it would have to be A. but you need to provide the connection to achieve that.
How would one calculate the connections to achieve that/where can I find info on that?
Do I just calculate the traction resistance of the upper rank anchors (in this case rebars anchored in Hilti HY-200). Can rebars realistically have the required moment capacity?

Actually, the right end is not a support. The Angles serve only as a guide for the underlying brick walls, and for some reason, it's not possible to use this wall as a support.

If "F" is the force on the wall, "L" is the distance between the left and right end, and "d" is the distance between top and bottom rebar, the pullout force would be:
F * L / d

The wall is sufficient, I just have some other restrictions preventing me from using it as a support.
The plan in the OP is in french. "MUR" means "wall".

As a side note, be sure to account for sufficient installation tolerance for "d" in your calculation. I'm assuming the wall you're attaching to is reinforced so there is a high probability they will hit rebar then move the new bars when trying to drill the new reinforcing in. The bars WILL NOT end up exactly where you expect them.
