- Abstract
The reinforced concrete tank in water supply system is a typical fluid-filled structure. There are liquid-solid couple effects and liquid sloshing in the fluid-filled structure under seismic actions. The existence of liquid storage changes the dynamic characteristics and seismic responses of the structure. The research objects are the ground circular tanks commonly used in water supply system. The finite element software ADINA is used to analyze the dynamic characteristics of the tanks firstly. Seven pairs of natural seismic records in the Wenchuan main shock are selected as bi-directional horizontal seismic inputs. The effects of water storage height, tank radius and ground motion characteristics on the maximum sloshing wave height of liquid surface and hydrodynamic pressure are analyzed according to the finite element analyses results. The distribution rules of the maximum sloshing wave height of liquid surface and hydrodynamic pressure are also given. The research results of this paper can provide references for tank seismic design.
