Abstract

A novel shaking table substructure testing method that includes interaction forces determined by actuator forces and shaking table dynamic parameters is proposed and validated. The seismic performance of a storage tank that incorporates soil-structure interactions is investigated by the method proposed in this article. The experimental results show that the proposed shaking table substructure testing method is an efficient alternative method of evaluating the seismic performance of a storage tank that incorporates soil-structure interactions. The experimental results show that the influence of the soil-structure interactions increases as the stiffness of the foundation soil decreases, which was demonstrated by the results showing that the displacement and acceleration responses of the storage tank decrease as the stiffness of the foundation soil decreases. Moreover, the influence of the soil-structure interactions increases as the liquid height increases, which was illustrated by the decreased displacement responses of the storage tank with increases in the liquid height. The maximum acceleration response of the storage tank occurred at the liquid surface height.
