: Provisions for the structural design of concrete tanks and similar structures, including considerations for strength, serviceability, and durability.

Assume you are designing a 20-foot diameter water tank in California using ACI 350.3-06.

ACI 350.3-06, "Seismic Design of Liquid-Containing Concrete Structures," provides essential procedures for calculating dynamic liquid forces on concrete containment structures during seismic events. It distinguishes between impulsive and convective (sloshing) forces, ensuring the structural integrity of environmental engineering infrastructure.

For engineers who need to apply ACI 350.3‑06 on a legacy project, or for those who wish to understand the evolution of the code, the document is still obtainable through the ACI website and through many technical libraries. As always, it is wise to check for any applicable errata and to verify that no more recent local code amendments have superseded its requirements.

While the general building code (ACI 318) covers standard buildings, ACI 350 specifically addresses . The "350.3" subset deals exclusively with the dynamic forces generated during an earthquake.

Several cities have used ACI 350.3-06 in actual infrastructure projects. For example, the City of Vancouver used ACI 350.3-06 to determine earthquake-induced hydrodynamic forces for critical water system reservoirs. Due to the critical function these reservoirs serve, it was recommended that they should be able to retain water following a design-level earthquake.

The ACI 350.3-06 standard, "Seismic Design of Liquid-Containing Concrete Structures and Commentary," provides essential engineering guidelines for ensuring environmental concrete structures withstand seismic forces, focusing on impulsive and convective hydrodynamic loads. This foundational document covers seismic design requirements, dynamic analysis for liquid-structure interaction, and detailed reinforcement standards to prevent leakage and ensure structural integrity during earthquakes.
