Shaking table tests were performed to clarify the dynamic behaviors of embedded tanks in soft ground due to strong earthquake motions. Special care was taken for the design of a soil container in order to reproduce ideal horizontal shear wave propagation in the model ground. Observed nonlinear responses of the embedded tanks due to various random motions were compared with the numerical results obtained from the axi-symmetric FEM analysis with equivalent linear method developed in CRIEPI. This method also applied to estimate the actual LNG tank during earthquakes. This comparative study reveals that the proposed numerical analysis gives a useful key to estimate the dynamic behaviors of embedded tanks during strong earthquakes.
