6x6xW2.9xW2.9 for the last couple of years because I was told you can walk
on this better during construction without it all ending up on the bottom.
If I might add to the line of questioning...
ACI 302.1R recommends that wwr should be discontinuous thru joints, it also
states partial discontinuance to maintain some load transfer capacity. I
have used a detail that calls for every-other wire to be cut at joints.
Never got a complaint but is this reasonable? I am wondering what many of
you do for the joints in slabs with WWR especially if you have a PEMB FDN
with hairpins.

I am not aware of any code required minimum reinforcement requirement =
for
slabs on grade in the US. The IBC does require a minimum of 3.5" slab =
in
section 1911, but places no requirements on reinforcement. Many people =
use
the minimum slab reinforcement ratios from ACI 318, but ACI 318 =
specifically
states that it does NOT apply to slabs on grade. As pointed out, the =
ACI
documents for SOGs are ACI 302 and 360, but neither are "mandatory"
documents, but rather guides or recommendations. I don't recall off the =
top
of my head if they offer recommendations on minimum reinforcement, but =
even
if they did those recommendations have no force of law. If you really =
want
to know, then say that word and I will dig them up and see if I can =
refresh
my memory.
