The static and dynamic lateral load responses of a 12-ft by 6-ft ground-supported cylindrical liquid storage tank model are compared. The static lateral load is produced by tilting the tank; the dynamic excitation is provided by the 20-ft square shaking table at the Earthquake Engineering Research Center, Univ. of California, Berkeley. Two types of foundation are studied, one rigid and one flexible. It is found that the rotational uplift mechanism is accentuated by the static excitation as compared with that produced by the dynamic input, particularly for the soft foundation material. However, the dynamic excitation amplifies the high-order distortional response, particularly when the tank is on the rigid base.
