Spiral reinforcement of round column, pitch/spacing
Spiral reinforcement of round column, pitch/spacing
(OP)
I am designing a reinforced concrete column, 24" diameter, with 1.5" cover. f'c = 3000 psi, fyt=60,000 psi.I find the minimum volumetric reinforcement ratio to be 0.069. By ACI-318, looks like I can choose from #3,4,or 5 bar for the spiral. With the diameter of the core as it is (21"), I get a very small clear distance, less than the minimum 1". Where have I gone astray?
Thanks in advance.
