OOP Shear for CMU Wall

Please excuse this very basic question. I'm putting aside fatigue and humbling myself to ask this question that I'm sure I once knew the answer to...

Checking CMU walls for out of plane shear. Yeah, I get it, it never really governs. I just want to recall that I remember this.

We use the same equation presented in TMS402 Equn 8-25 for non-special walls. This gives you and Fvm.

Say the wall is grouted at 48" o.c. intervals. What's 'd' do I use to calculate the capacity in linear feet. I want to see the value in lb/ft, not stress.
(All the examples I went back to check do illustrate this problem with solid walls, so it's straightforward).

It would be the same depth as it would be with solid walls: extreme compression fiber to center of bar.
 
Yes, but how does Anet in terms of stress relate to 'd' when the wall is partially grouted.

So you're saying I would just do Fvm x d (as you referenced) x 12"/ft for the capacity in lb/ft? This doesn't seem right because we know the area is less than solid grouted.
