D for a masonry shear wall
Posted 03 April 2012 - 05:11 PM
SERM and 2006 structural seismic uses the total wall width. (d sub v)
Susan Frey and an old NCEES Structural II practice exam use d (depth to reinforcing)

Additionally, note that the MSJC explicitly uses the d term, not dv, in the shear stress calc (even though it does define dv in the notation section).
Either way, the difference is fairly minimal unless the wall is not long, so I'd err on the side of being slightly conservative and using the reinforcement depth.

Trust Sue Frey
This may very well be the best advice ever given in reference to masonry design. I took the Kaplan review course and I am absolutely in awe of Sue Frey. If I were anywhere near where she teaches, I would take every class she taught.
