Abstract: In this paer, effects of hy drostatic pressures on the natural frequencies of cylindrical liquid storage containers are analyzed by using nonlinear strain-displacement equation of the shell, and the system matrix equation of motion is derived with an additive stiffness matrix due to the presence of the initial stress field.A comparison betw een the computed dynamic characteristics and the results from experiments is made, showing that they are in good agreement.

Key words: liquid storage container, hydrostatic pressure, natural frequency
