Detailing Rebar!!?
Detailing Rebar!!?
(OP)
I'm a piping designer contracted on a small project; I'm "pressed" into doing the foundation drafting on this project too. I've been around awhile and I've seen afew foundation details (but obviously not a designer in this discipline). I'm working with an engineer on this project, he's contract too and "away" at present. He's give me the basic info, and I'm doing my best to get it right, but I have afew basic drafting issues I need help on.
First is when you bent rebar obvious there's a radius at the bent, is there a minimum/normal radius to try to achieve in relationship to rebar size (#8)? ...This is a 90 deg. bent & at the corner of foundation. Also when you're looking at a section cut showing the rebar cage, at the corners of this cage, what is "normal" placement of rebar that runs perpendicular to this loop ...at the corners? Is it at the tangent of the bent? ...OR centered in the radius on the perimeter? ...Hopefully the experts can under stand my issues here!?? Any help would be appreciated!

#8 bar would usually be detailed for a 3" inside radius on the bend, but there are end hook lengths, etc that need to be considered too. The engineer probably should have noted all this if you aren't familiar with it.
The bars in the corners of the section (longitudinal) should be tied to the "loop" bars, so show them on the inside of the bend.
