Aci-350.3-06.pdf ((top))
ACI 350.3-06 provides detailed step-by-step procedures for calculating these forces based on the mapped spectral response accelerations (S_s and S_1 obtained from seismic ground motion maps) and the tank's specific geometry. The document includes comprehensive equations and charts for engineers to determine the impulsive and convective weights, their centers of action, and the natural periods of the tank-liquid system. It also gives guidance for other critical loads, such as the dynamic earth pressures on partially buried tank walls.
As noted earlier, ACI 350.3‑06 has been superseded by , titled "Code Requirements for Seismic Analysis and Design of Liquid‑Containing Concrete Structures and Commentary," first printed in October 2021. The newer edition reflects changes in referenced codes (updating from ASCE 7‑05 to ASCE 7‑16) and aligns with the reorganization of ACI 350 itself, where seismic provisions now reside in Chapter 13 instead of the former Chapter 21.
