ACI 350-06 Minimum Wall Thickness Requirements
(OP)
Hey guys,
Chapter 14.6 Minimum Wall Thickness
I'm designing a 110ft x 45ft x 10ft tall concrete cooling tower basin. Above ground. The owner wants it designed per ACI 350. Hypothetically, if my analysis tells me that an 18" thick wall is sufficient for flexure and shear, do I have to meet the "nor less than 1/30 the least distance between members that supply lateral support" requirement?
That would be 110ft x 0.0333 = 3'-8" thick!
If it was a 60ft long wall, it would require a 2'-0" thick wall! Can I get around this requirement?
I know the answer to this would be buttresses, wingwalls, or pilasters, but I'm trying to get away without them.
Who can help? Thanks.

If you feel the need, economize elsewhere, by selecting less expensive details, for a quicker build, easier construction, and more durability.
