ABSTRACT
ABSTRACT: A 3-D transmitting boundary in a cylindrical coordinate system is applied to obtain the earthquake response of a cylindrical liquid storage tank installed in the watersaturated transversely isotropic ground. The effects of the far-field region are represented by the transmitting boundary. Using finite elements, models are developed for the flexible tank wall and the near-field region of the ground. The motion of the contained liquid is modeled using boundary elements. Hybrid time domain-frequency domain analysis is used to obtain direct time-domain representation of the earthquake response of the system. Numerical results are given to illustrate the results of this method of analysis. A rigorous two-phase transversely isotropic medium model has to be employed to accurately represent the dynamic behaviors of a structure on the water-saturated transversely isotropic strata.
