Dynamic Analysis of Reinforced Concrete Rectangular Liquid Storage Structures Considering Liquid-structure Interaction

DU Yong-feng,SHI Xiao-yu,CHENG Xuan-sheng(School of Civil Engineering,Lanzhou University of Technology,Lanzhou 730050,China)  
Because influence of liquids,the dynamic reponse of liquid storage structures are different with other kind of structures.In this paper,taking into account the action of rebar in concrete materials,the current finite element software ADINA is used to do finite element simulation for the reinforced concrete rectangular liquid storage structures.The influences of gravity wave of the liquids surface,the stiffness of wainscots and the shape of the structures on the dynamic response with liquid-structure interaction are discussed,and the dynamic responses are also discussed in the action of unidirectional,bidirectional and three-directional coupling seismic actions.The result provides the theoretical basis for reinforced concrete rectangular liquid storage structures.
