Seismic resistance requirements for anchored liquid storage tanks are clearly defined in dedicated design provisions. But are these provisions applicable to their unanchored counterparts? Researchers funded under the LIFTING TANKS project developed mathematical models in order to find out.
Being essential components of lifeline and industrial systems, liquid storage tanks need to be kept safe. But the harsh truth is that they aren’t: earthquake-caused failures have often resulted in spillage of toxic materials over the years, sometimes leading to disastrous effects.
