It was unclear to me, that's why I consulted the experts here. I see now in section 14.1.2 where it says "Cantilever retaining walls are designed according to flexural design provisions of Chapter 10..."
Thanks all for your input.

The owner wants to maximize speed of construction and economy I'm exercising due diligence. Out of all of the references I have, this is the only thing that gives a minimum thickness based solely on length of unsupported wall.

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...
Or anybody.
LC 9-6
U = 0.9D + 1.2F + 1.6W + 1.6H
Do I need to determine Sd for each load case within the load combination?
For dead load:
Sd = (phi*60ksi) / (load factor*20ksi)
Sd = (0.9*60) / (0.9*20) = 3.0
Therefore
Sd*U = (0.9)(3.0)D + 1.2*Sd*F + etc...
Am I thinking of this correctly?
JAE,
Still a little confused...
I have read your other threads as well. Can you provide an example using ACI 350-06 LC 9-6?
say fs = 20ksi, fy = 60ksi, phi = 0.9 (flexural case)
What is the Sd factor for LC 9-6?
Thanks
