Seismic Loads Influence Treatment on the Liquid Hydrocarbon Storage Tanks Made of Nanocomposite Materials

Abstract

The liquid hydrocarbon storage tanks are the objects of environmental danger. It is necessary to perform additional calculations and develop appropriate design solutions to minimize the risks of their accidents in the event of the earthquake or explosions. The degree of damage to the environmentally hazardous object during the earthquake depends not only on the seismic effects level, but also on the quality of seismic design and construction. The possibility of exposure to smaller but more frequent and prolonged seismic loads caused by technogenic and natural factors has not been sufficiently taken into account in tanks designing for the environmentally hazardous liquids storage. The composite materials using with nanoinclusions in tanks for storage liquid hydrocarbons, allows to increase the reliability of tanks under seismic loads and extend their service life under the influence of natural and technogenic influences of various origin. The results of the calculations have been shown that the use of composite materials with nanoinclusions in the steel spheres form is the best option for environmentally friendly operation of tanks under seismic loads.

Seismic Response Analysis of Underground Large Liquefied Natural Gas Tanks Considering the Fluid–Structure–Soil Interaction

“…The study of the free and forced oscillations of an elastically rotating shell partially filled with an ideal incompressible fluid has also been explored. Sierikvoa [12] utilized Ansys to analyze the response patterns of steel tanks containing nanocomposite materials under seismic conditions. N. Farasat et al [1] compared the displacements and stresses of aboveground water tanks and underground tanks under seismic loads, revealing that underground tanks have fewer displacements and stresses, indicating their relative safety.…”
