The in the file name indicates the year of publication: 2006 . As of 2024-2025, this standard has been superseded by newer versions (specifically ACI 350.3-20). However, the 2006 edition remains actively used for several reasons:
In the field of civil and structural engineering, the design of liquid-containing structures—such as water treatment plants, reservoirs, and wastewater facilities—presents a unique set of challenges. Unlike typical buildings, these structures must account not only for the inertial forces of the structure itself during an earthquake but also for the complex hydrodynamic forces exerted by the contained liquid. The American Concrete Institute’s , titled “Seismic Design of Liquid-Containing Concrete Structures and Commentary,” serves as the definitive standard for addressing these challenges in the United States.

ACI 350.3-06 establishes requirements for the seismic design of environmental concrete structures, using Housner’s model to analyze impulsive and convective liquid behavior. It outlines specific calculations for lateral forces, recommending the square-root-sum-of-the-squares (SRSS) method for combined seismic loading.

ACI 350.3-06 is widely used in the design of reinforced concrete structures in areas prone to earthquakes. However, the code is not without its limitations, and there are ongoing efforts to improve and update the provisions. Some future directions for research and development include: Unlike typical buildings, these structures must account not
ACI 350.3-06, "Seismic Design of Liquid-Containing Concrete Structures," provides essential, specialized criteria for calculating seismic pressures on liquid-retaining tanks, dividing forces into impulsive and convective components to ensure structural integrity. This standard mandates specific considerations for cracking, watertightness, and vertical acceleration, acting as a crucial, necessary supplement to standard building codes like ACI 318.

ACI 350.3-06 is applicable to a wide range of reinforced concrete structures, including:
