Foundation Wall Reinforcing

Foundation Wall Reinforcing

Foundation Wall Reinforcing

Checking over some drawings done by an architect. They have a foundation wall with #5@48o.c., which I dont see as doing anything. Would you just consider it plain concrete as designed? Interior slab on one side, outside grade on the other.

How do you folks handle this type of detailing?

RE: Foundation Wall Reinforcing

That wouldn't meet spacing limits of rebar for flexural design. Per ACI 318-08 7.6.5: 7.6.5 — In walls and slabs other than concrete joist construction, primary flexural reinforcement shall not be spaced farther apart than three times the wall or slab thickness, nor farther apart than 18 in.

So yeah, consider it as plain concrete. That reinforcement is just decoration. It doesn't do anything for flexure or crack control.

RE: Foundation Wall Reinforcing

Spacing is greater than that for temperature steel in many jurisdictions.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?


RE: Foundation Wall Reinforcing

Probably per International Residential Code rather than ACI 318.

RE: Foundation Wall Reinforcing

In our environs where frost penetration is 6', that detail would likely fail.

RE: Foundation Wall Reinforcing

Yup, definitely based on the IRC.

RE: Foundation Wall Reinforcing

Thanks everyone. Its a small commercial building, It checks un reinforced. I have had bigger houses than this with less reinforcing.
