Abstract:

Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate support, and settlements can be estimated with reasonable accuracy using conventional procedures. Observations of the behavior of steel tanks during hydrostatic tests and during service provides a basis for how much settlement and differential settlement can be tolerated under various conditions. Case histories of tank construction and rehabilitation afford examples of techniques that can be used to reduce the magnitudes of tank settlements, or to repair tanks and tank foundations where excessive settlement has occurred.
