ACI 350.3-06 represents a vital synthesis of theoretical hydrodynamics and practical structural engineering. It provides the rigorous framework necessary to protect water and wastewater infrastructure—which is indispensable for community recovery after a disaster—from seismic devastation.

ACI 350.3-06, "Seismic Design of Liquid-Containing Concrete Structures," provides essential guidelines for calculating seismic forces on environmental concrete tanks, focusing on both impulsive and convective hydrodynamic loads. The standard addresses unique structural demands, such as tank flexibility and fluid sloshing, to prevent damage from lateral pressure and roof impact.

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.

Engineers working on new projects are generally advised to use the most current edition. However, ACI 350.3‑06 remains relevant for:

Before the development of ACI 350.3, the seismic design of liquid-containing structures was not adequately covered by leading national codes and standards. The national model building codes (such as IBC, UBC, SBC, BOCA, and ASCE-7) either refrained from covering the seismic design of liquid-containing structures or provided only simple static-force equations for calculating base shears. ACI 350.3 was developed to fill this gap with a rigorous yet practical approach.

The seismic design philosophy outlined in ACI 350.3-06 is based on the following principles:
