Masonry Shear
Masonry Shear
(OP)
I have an 8" masonry wall reinforced at 40" o.c. with d = 12'-10". I am trying to use this wall as a shear wall (driving 41kips of shear through the wall). The code states fv=V/bd. Is bd based off the gross area of the wall or the net area based on my grouting requirements?
The code seems to imply it's based off the gross requirements, but net makes more sense to me.

Amrehein has a table showing the effective thickness based on the grout spacing. Use that effective thickness in your shear calculations.

See also the attached tables and figures. These show the ares used for flexure, axial and shear.
