One of the most practical sections in ACI-350.3-06.pdf is Chapter 6: Freeboard . It calculates the maximum vertical height of sloshing waves. If the tank roof is too low, the liquid will slam into the roof, causing structural damage or overflow. The code mandates a minimum freeboard based on the site's (S_D1) and tank radius.

ACI 350.3-06 is a technical standard titled Seismic Design of Liquid-Containing Concrete Structures and Commentary . Published by the American Concrete Institute (ACI)
is the definitive industrial standard published by the American Concrete Institute (ACI) for the seismic design and analysis of liquid-containing concrete structures . Titled “Seismic Design of Liquid-Containing Concrete Structures and Commentary,” this 67-page technical code bridges the structural loading demands of environmental facilities with the strict fluid dynamics of sloshing containment bodies. It calculates the maximum vertical height of sloshing waves
