Seismic Behavior of Baffled Liquid Storage Tank Under Far-Field and Near-Field Earthquake
The liquid storage tanks (LST) are one of the essential civil structures. The inter-action of LSTs with an earthquake during its service life is a critical and crucial factor that cannot be ignored. The present study describes effect of the earthquake on the response parameters of LSTs. Depending on the nature of the earthquake these responses can increase or decrease. The study is further extended by implementing the passive control device. A vertical baffle plate is placed at the base of the tank. The non-linear dynamic analysis of the LST is performed on the ABAQUS. The response quantities of interest include top board displacement, Von-Mises stress, shear force, overturning moment, wave height, and hydrodynamic pressure in the tank. The results show that wave height for the different earthquakes can yield a difference of about four times. The baffle plate can significantly impact the sloshing height. The maximum reduction of 77% in wave height for far-field earthquake is present. However, the presence of the baffle increases the shear force response of the tank.
