Abstract
Liquid-filled tanks are important infrastructure for the storage of water, chemicals and fuels, such as oil and liquefied natural gas (LNG). Many such large-scale tanks are located in regions with high seismicity. Therefore, very frequently base isolation technology has to be implemented to reduce the dynamic distress of the superstructure. In structural analysis software base isolators are modeled utilizing special nonlinear isolator elements. Global damping modeling of seismically isolated structures is a crucial issue, since improperly defined damping may worsen significantly the dynamic analysis results, mainly due to the so-called "damping leakage" phenomenon. For this purpose, this work is focused on the impact of damping modeling approach in the dynamic response of liquid storage tanks isolated via single friction pendulum bearings (SFPBs) under strong near-fault ground motions.
