Joel - I tried to configure (imagine) a non-prestressed concrete tank that had H^2 / Dt > 50. Hard to do. For both the considerations of the combined shear + flexural demand at the base, and shrinkage, tall non-prestressed concrete tanks are uncommon, and I certainly would try to persuade you toward either steel or prestressed (DYK / DN) Type …See thread507-434895: Tension Field Action - End panels in Old Codes.

Efficiency (measured in stiffness or strength per unit of weight) is not highest with compact sections - it is actually quite the opposite.
