Re: What is #3 Rebar equivalent for 6x6/W2.9xW2.9 WWF

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dennis,
 
I have an answer that differs from Randall's.  According to Table Reinforcement 4 of ACI-340R-97, 6x6/w2.9x2.9 has a steel area of 0.058sq.in./ft.  [0.029sq.in./6"]  That's 0.  0.11 x 12/0.58 = 22.75in spacing.  That's not much steel in a 6" slab is it -- I would go with Randall's 12" spacing.
