Shear Friction Reinforcement VS. Max Steel Area
Shear Friction Reinforcement VS. Max Steel Area
(OP)
Does reinforcing area used for Shear Friction according to ACI 318 section 11.7 count towards the maximum steel percentage for 0.75pb?

RE: Shear Friction Reinforcement VS. Max Steel Area
Can you expand a bit on your wall corner example? Usually the reinforcement used for bending is orthogonal to the shear reinforcement in a bending member since the shear cracks are usually at an inclined angle to the flexural "beam" and thus the shear reinforcement is not aligned with the flexural. Thus there is no conflict.

But I wouldn't use stirrups in a wall--I would thicken the wall as hokie66 suggested.

in certain circumstances. You need to have a
cold joint or a reasonable expectation that a crack will occur along the plane in question - a SHEAR plane. Diagonal tension cracking doesn't count as a shear plane.
