摘要：In this paper, the liquid-solid interaction dynamic finite element integral models of a reinforced-concrete rectangular liquid-storage structure are established to obtain the liquid-solid interaction seismic response of an isolated overground rectangular reinforced-concrete liquid-storage structure. It is assumed that the liquid is incompressible and the influence of gravity wave on the surface of liquid is considered. Some mechanical properties, such as the liquid sloshing height, wallboard displacement and equivalent stress under seismic action and the seismic response under different liquid level of the single cell liquid-storage structure, are discussed, by considering factors of the nonlinear dynamic characteristic, element selection, seismic input, mesh density, convergence and liquid-solid interaction. The results of numerical examples indicate that: the peak displacements of the isolated structure under different earthquake intensities are basically the same, the displacement of the wallboard and stress increase with the increase of seismic intensity, and the lower the level of the liquid is, the less the amount of liquid is and the greater the shaking amplitude is, the greater the stress and displacement of the wallboard are.
