: Represents the portion of the stored liquid that moves in unison with the structure. This component is assumed to be rigidly attached to the tank wall and contributes to the overall base shear and overturning moment.

Crucially, the commentary guides the engineer on limiting steel stress to control crack widths. This ensures that even if the concrete stresses are within limits, the structure remains watertight.

Liquid-containing structures (e.g., water tanks, clarifiers) must remain leak-proof and stable during earthquakes. ACI 350.3-06, “Requirements for Static and Dynamic Analysis,” is a specialized code for environmental engineering concrete structures. Unlike ACI 318-05, ACI 350.3-06 incorporates hydrodynamic effects explicitly. This paper applies its equivalent lateral force method to a typical tank. ACI-350.3-06.pdf

ACI 350.3-06, published by the American Concrete Institute, is a critical engineering standard for the seismic design of liquid-containing concrete structures, providing methodologies to calculate dynamic fluid pressures. The standard utilizes a two-mass model to analyze impulsive and convective (sloshing) forces, ensuring the structural integrity of tanks and reservoirs. For more information, visit docs.cntd.ru .

The standard outlines a step-by-step procedure for analyzing tanks (typically ground-supported rectangular or circular tanks): : Represents the portion of the stored liquid

: Guidelines for construction techniques, including formwork, placement of reinforcement, concrete placement, and curing.

⚠️

The document assumes that the structure is located in a seismic design category (SDC) B or higher, as defined by the International Building Code (IBC) or the American Society of Civil Engineers (ASCE) 7-10 standard.
