Reinforcement Spacing in Concrete Walls
Reinforcement Spacing in Concrete Walls
(OP)
Hi all
First time poster. Been using previous posts for info for forever!
Question is this: if ACI 318 (7.6.5) and CSA A23.3-2014 both limit reinforcement spacing to 3x the wall width maximum, why do Logix and FoxBlocks tables permit spacing well beyond this? How do they do it? FoxBlocks even has technical bulletin: 1.05.06 which reinforces this. I'm in Canada so we have to abide by CSA standards and don't have the ACI and IRC competing against each other. But from what I can tell, the IRC allows spacing beyond this as well (even though it is supposed to parallel ACI-318). And in reading the commentary for 318-11 it actually says (in regards to 7.6.5.) that using spacing larger than the minimum may be desirable.

Their tables are perhaps for residential homes, basements, etc. When using IFC systems, we always design to ACI 318 and ignore those tables.
RE: Reinforcement Spacing in Concrete Walls
I admit I let a little confusion creep in: IBC vs IRC.
Up here we have the NBC and it covers both.
Does the IRC not have such a requirement for limiting reinforcement to 3x the wall width?
I am specifically referencing residential concrete walls.

Our firm actually used to develop the Reward Wall system tables years ago.
