When using this standard, engineers must perform specific checks that are unique to liquid-containing structures:

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

is more than a dusty code from the mid-2000s. It is the technical bridge between fluid dynamics and earthquake engineering. It protects communities from the specter of a fractured water tank during a major quake—an event that could leave a city without drinking water or flood a neighborhood with raw sewage. When using this standard, engineers must perform specific

The code applies to rectangular and circular concrete tanks, reservoirs, and basins. It explicitly covers structures containing liquids with mass density up to 75 lb/ft³ (similar to water). Importantly, it excludes pressure vessels and buried tanks where soil provides restraint. When using this standard
