If you are using this for a current project, verify whether ACI has superseded it with a newer version (e.g., ACI 350.3-20 or a revision). The 2006 edition may still be permitted by reference in some older specifications, but many engineers today rely on ACI 350’s durability chapters or alternative guides (e.g., from WEF or ASCE).

The American Concrete Institute (ACI) publication 350.3-06 provides guidelines for the seismic design and detailing of concrete structures. This standard is crucial for ensuring that concrete structures can withstand seismic forces and maintain their structural integrity during earthquakes. In this feature, we will review the key aspects of ACI 350.3-06 and its significance in designing and detailing concrete structures for earthquake resistance.

For tanks with interior decks or baffle walls, the code specifies how to transfer seismic forces through the concrete diaphragm to the lateral force-resisting system. ACI-350.3-06.pdf

The standard introduced several key shifts from traditional rigid-tank methodologies: ACI-350 3-06 Seismic Design of Liquid-Containing

By following the guidelines and requirements outlined in ACI 350.3-06, engineers can design and detail liquid-containing concrete structures that are safe, resilient, and sustainable. If you are using this for a current

Furthermore, users should be aware that , namely ACI 350.3-20 , which was published in 2021. The 2020 edition is the current, updated standard and should be referenced for new designs where possible. However, ACI 350.3-06 remains critically important for the evaluation and maintenance of existing structures designed under that code, and it serves as a valuable historical reference to understand the evolution of seismic design provisions for liquid-containing structures.

, titled "Seismic Design of Liquid-Containing Concrete Structures and Commentary," is a standard published by the American Concrete Institute (ACI). It was reported by ACI Committee 350 and released in 2006. The document is 67 pages long and is available for purchase as a PDF download through the ACI website. This standard is crucial for ensuring that concrete

ACI 350.3-06, " Seismic Design of Liquid-Containing Concrete Structures and Commentary ," is the essential technical standard for analyzing seismic loads on concrete containment structures. It provides a two-degree-of-freedom dynamic model to calculate impulsive and convective forces, ensuring stability and preventing damage from sloshing liquids.

ACI 350.3-06 differs from standard building codes in its philosophy regarding load combinations. It utilizes strength design (Load and Resistance Factor Design, LRFD) but applies it through the lens of environmental durability.
