Abstract:

To study the dynamic responses of a buried horizontal double-layer SF-type liquid-storage tank considering liquid-solid interaction, a three-dimensional finite element model of the double-layer buried horizontal liquid-storage tank is established, and the model is calculated and simulated by using FEM (finite element method). The results show that the double-layer buried horizontal SF-type liquid-storage tank is a composite multi-layer structure; thus, the dynamic responses of the inner layer, interlayer and outer layer are different under the same earthquake wave: the tank wall displacement of the interlayer is the maximum, whereas that of the outer layer is the minimum; the tank wall equivalent stress of the inner layer is the maximum, whereas that of the outer layer is the minimum; and the distributions of strain and velocity in the inner and outer layers are also different. The double-layer SF-type oil-storage tank has different dynamic response rules under the actions of the El-Centro wave and the Lanzhou wave. Compared with the El-Centro wave, the dynamic responses of the double-layer oil-storage tank are more significant under the action of the Lanzhou wave. The dynamic responses of the horizontal double SF tank are found to be closely related to the spectral characteristics of the seismic wave and exhibit different dynamic responses under different earthquakes.
