摘要 | A rectangular liquid-storage structure is often located on a foundation through bottom plates, it is necessary to study its dynamic characteristics considering the foundation effect. Here, the limit height of small amplitude sloshing was defined, the simplified model of the rectangular liquid storage structure was established. Using artificial boundaries to simulate foundation effect, the finite element calculation model was established. Sloshing heights corresponding to two kinds of models were compared to verify the rationality of the simplified model. Based on the potential flow theory, the dynamic responses of the rectangular liquid-storage structure under different boundary conditions, different seismic waves and different seismic acceleration amplitudes were studied. The results showed that the sloshing height trends of the two kinds of models are consistent, and the difference of the maximum sloshing heights is small; in the range of small amplitude sloshing, there is a linear relationship between the maximum sloshing height and the amplitude of earthquake acceleration; after considering soil-structure interaction, the tank wall horizontal displacement, tank wall effective stress and liquid sloshing pressure have a larger level of reduction, but the foundation effect has little influence on liquid sloshing height. © 2017, Editorial Office of Journal of Vibration and Shock.
