New to Old Concrete Bond
(OP)
I can't find it, but I would swear in one of the many shear friction discussions someone mentioned that one of the Codes (not ACI) had a bond stress value or a way to calculate it. Am I remembering wrong, or does this exist? IF so what Code was it?
Thanks
Thanks

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

In the Canadian code, we separate the two shear friction mechanisms (cohesion & particle interlock). As a result, you can use cohesion on its own if you've good the stomach for it. For roughened concrete, you get 0.25 MPa; for non-roughened, you get 0.5 MPa.
The attached paper may be of interest to you.
