Abstract:In this paper, ABAQUS finite element software is used to simulate the dynamic response under full tank level, 3/4 full tank level and 1/2 full tank level three conditions for large liquid storage tank in earthquake. The interaction between the tank structure and liquid is simulated through fluid–solid coupling method and the dynamic buckling characteristics were studied at the same time. The results showed that: the state of full of liquid is relatively the most dangerous in three conditions. The higher the liquid level, the more intense the fluctuations of liquid surface are under the same earthquake acceleration spectrum, the larger the stress and deformation of the tank wall and ribbed stiffeners. The buckling of lower tank wall occurs only in the full tank condition. Energy-time history curve shows that the moment of plastic dissipation energy significantly increasing is that of plastic dynamic buckling occurring. It is suggested to increase the stiffness of the lower ribbed stiffener and thicken the plate at the lower part of the tank wall.
