Abstract

 This study presents a reliable and effective idealization scheme for the free vibration analysis


 


of buried cylindrical storage tanks. The three dimensional problem is transformed into a two


 


dimensional one by using a semi analytical finite element procedure. Conical shell of


 


revolution element is used. to represent the cylindrical wall, top plate, and bottom plate of the


 


tank by an appropriate method. The Combined effect of structure-soil-fluid interaction is of


 


primary importance as concluded in this work. The soil medium is idealized by the elastic half


 


space model, that is, linear springs are assumed to represent the structure-soil interface, added


 


masses and viscous dampers of soil are also included. The liquid region is treated analytically;


 


also analytical integration is used to got the added stillness and mass matrices for hydrostatic


 


and hydrodynamic pressure effects, respectively. The free vibration characteristics of the


 


liquid storage tank are validated against experimen.tal and theoretical results available in


 


literatures.
