Special Reinforced Masonry Shear Walls

[AlpineEngineer]

I am designing a masonry building in SDC D utilizing special reinforced shear walls. My shear walls are relativly long (50' in some instances)and I've run calcs and find that I dont even need horizontal grouting/rebar for shear because i am so long; however ASCE/MSJC minimums are grouted horizontal w/ #4 at 24" min for SDC D. But, I don't know that I have ever seen partially shear walls in SDC D and I don't like the feel of partially grouted shear walls.

What would you typically expect? Fully grouted shear walls? Building is simple, rectangle (50'X165'), flexible diaphragm, 8" CMU running bond, f'm=1500, fy=60ksi, 15' tall walls, low slope roof, Sds=0.58.

I see in MSJC for stack bond they require solid grout in SDC D, but can find no rqmnt for running bond (my case).
thx

I've been told that contractors prefer solid grout in lieu of grouting every third course.
