This partly depends on what you mean by "equivalent
layout". From a strength standpoint the WWF is made in accordance with
ASTM A185 which kicks you over to ASTM A82 for the actual wire. The
yield strength of the wires are 65 ksi when used to make mesh. The
equivalent area of the 6x6 W2.9 mesh is 0.058 sq in/foot so the equivalent
area of #3 bar would be 0.058 x 40/65 = .036 sq in/foot or about #3s at 37
inches each way. This may not be advisable for crack control so reduce
spacing to what you feel comfortable with.

|What is #3 Rebar
equivalent for 6x6/W2.9xW2.9 WWF|
Sorry, I forgot to give you the grid spacing on the WWF –
it’s 6x6/W2.9xW2.9 – this is most commonly used WWF in our area for SOG’s – no
expansive soils to worry about, all silty sand – no organics.
tell me what the equivalent layout is for #3 Fs=40ksi rebar in a 6” thick
concrete (f’c=2,500 psi) slab on grade to replace the normal W2.9xW2.9 Welded
