DAMPING OF LIQUID SLOSHING IN STORAGE TANKS FROM SEISMIC LOADS

Abstract

Seismic loads acting on reservoirs partially filled with liquid, cause the sloshing phenomenon in it. The partially filled tanks could be exposed to particularly strong sloshes. The strong movement of the liquid could create the high localized pressure of the liquid on the tank walls, which in turn could lead to the tank structure destruction or to the loss of its stability. The ingress of hazardous liquids from the tanks for their storage into the environment and their further spread to the settlements territory could cause mass poisoning of people and animals, lead to environmental components pollution. Liquid spills could lead to explosions and fires that could spread to nearby reservoirs and surrounding areas. As the storage tanks are the huge supply of combustible substances, the fire could lead to serious consequences. The aim is to prevent emergencies and the negative impact on the environment in the case of sloshing environmentally hazardous liquids in tanks under the seismic loads action.
