Why is seismic risk assessment important for storage tanks?

Earthquakes, as a natural threat affecting all structures, also trigger events like fire and explosion in storage tanks. Therefore, the assessment of seismic risks for storage tanks, the prediction of damage, is crucial for both existing and newly constructed tanks.

What is seismic performance of industrial structures?

Seismic performances of industrial structures. Liquid storage tanks. Spherical shaped tanks. Horizontal-cylindrical tanks. Seismic fragility curves. Storage tanks are structures widely employed in various chemical and petroleum industries for the storage of liquids and gases.

Can energy-dissipating devices reduce seismic response to liquid storage tanks?

For seismic response mitigation of liquid storage tanks, some energy-dissipating devices have been proposed by researchers from the early research works in this field.

How does a tank model affect seismic response?

The numerical model examines the seismic responses of a tank model equipped with three control mechanisms; two base isolation mechanisms and a hybrid system. The model equipped with the hybrid system resulted in the least base shear of the tank and lower values of both accelerations and displacements.
