英文摘要	Assuming that the liquid is incompressible, and considering the effect of the surface gravity wave of the liquid, the liquid sloshing height, wallboard displacement, equivalent stress equiv-alent strain, and the seismic response at different height of liquid level through setting up the dynamic finite element model of the liquid -solid interaction about the over-ground concrete rectangular tanks of seismic isolation and non-seismic isolation. According to the comparison analysis: the isolation pad markedly reduces the liquid sloshing height; the peak wallboard dis-placement and stress increase with the increase of earthquake intensity, and the peak wallboard displacement, and stress of liquid-storage structure under seismic load are much lower than that of tank under non-seismic isolation; the liquid sloshing amplitude increases with the de-crease of liquid level height; generally speaking, the wallboard displacement decreases with the reduction of the liquid level height; in the case of non-seismic isolation, the lower the stress is, the less the liquid is; while in the case of seismic isolation, the lower the stress is, the more the liquid is. © 2015 ejge.
