Abstract
It is recognized that an advanced industrial country (such as S. Korea) makes extensive use of fluid filled tanks to store  highly flammable (and environmentally hazardous) fluids. Furthermore, the built environment of modern metropolises (such as Seoul and Pusan) is dominated by high-rise buildings. The dynamic response of such structures (i.e. fluid filled tanks and high-rise buildings) is characterized by long characteristic periods (T > 1 sec). This fact alone makes these types of structures vulnerable to basin-induced surface waves the energy of which normally is carried by long periods (T > 1 sec).
We briefly review a recently proposed effective method to identify and separate surface waves from recorded accelerograms. Such a capability allows us to separate surface waves and study their characteristics (e.g. amplitudes, dominant periods, etc.). Then, we outline how to extend the existing stochastic method of synthesizing earthquake strong  motion accelerograms so as to incorporate surface waves.
Finally, we present simple mechanical analogues (which have been proposed in the past) that can be used to simulate the dynamic response of fluid-filled tanks. Examples of the dynamic response of such structures to synthetic motions are presented. A similar approach, which is under development for high-rise buildings, is outlined.
