A simple but effective modal solution based on the underlying ideas of the hierarchical finite element method is presented for evaluating the free vibration characteristics of vertical, thin, circular cylindrical shells, partially or completely filled with liquid and subjected to any variationally c

The natural frequencies of liquid in a liquid-"lled cylindrical rigid tank without and with ba%es are evaluated. An annular plate is used as a ba%e, which is "tted to the inner periphery of a cylindrical tank. Both rigid and #exible ba%es are considered. Finite elements are used to discretize both t
This paper is concerned with the re"ned numerical techniques for the seismic analysis as well as the free vibration analysis of liquid-storage tanks. In the numerical formulation of accurate added-mass matrix, for the construction of uncoupled-separated structural dynamic system, the liquid free-sur
