is a standard that prescribes procedures for the seismic analysis and design of liquid-containing concrete structures . Its primary focus is the "loading side" of seismic design—meaning it provides the methods to determine the magnitude and distribution of seismic forces that the structure must resist. It is intended to be used as a companion to ACI 350-06 , specifically complementing Chapter 21 and Section 1.1.8 of that code which govern the "resistance side" of design (i.e., detailing the concrete to withstand those forces).

By clearly defining the behavior of impulsive and convective liquid masses, and by providing specific provisions for concrete durability and anchorage, the standard ensures that these massive, heavy, and critical facilities remain safe, stable, and functional. For any engineer tasked with designing a reservoir or treatment tank in a seismic zone, ACI 350.3-06 is not merely a guideline but an essential tool for engineering excellence and public safety.
