overhang truss pieces attached to coreslab.

[lubos1984]

Good Morning and hope everyone had a good weekend.

Contractor has requested if a design detail can be developed to attach overhang truss pieces to a tall wall 10" thick coreslab. I've attached pictures below for reference. This is in a high snow load area in the Niagara region so snow drift will be an issue to consider.
Question regarding connecting truss pieces to a coreslab. I was thinking of using two angles top bottom - bottom angle providing bearing and attached to slab , top angle is abit more tricky in terms of connecting top of truss to angle, any suggestions ? perhaps screws top-down from angle to truss? Re Connecting angle to coreslab perhaps using butterfly type anchors ?
Suggestions are appreciated. Thank you for your help.

This project looks fairly well along for this issue to just be coming up now.

What's your position in the project? Engineer of record? Construction Engineer?

I assume the core wall has been checked for the moment on it from these trusses?

What did the truss design assume for support characteristics?

What was the original intended detail?

I recommend posting a detail of the section. Even if it's incomplete with respect to the connections, it will help us greatly to see the spatial relationships between things.

My gut feel based on what you've shown us so far is:

1) Grout the plank ends and fasten a ledger there. Attach the truss bottom chords to that with hangers or something conventional in the wood to wood world.

2) Attach the truss top chords to the wall above.

Obviously, doing this would require opening the building envelope back up which may be objectionable. I'm not sure if your intent is to create a moment connection between the slab and the trusses but, if it is, I'm pretty skeptical that can be made to work unless I'm misreading the situation.
