中文摘要：
由于其中液体的影响，贮液结构的频域特性与普通结构不同。本文采用通用有限元软件ADINA，综合考虑材料中混凝土和钢筋的作用，对钢筋混凝土矩形贮液结构进行三维有限元模拟。分别探讨了液体表面重力波、液位高度、壁板刚度以及结构尺寸对系统液固耦合频域特性的影响，为矩形贮液结构的研究及设计提供理论依据。
英文摘要：
Because the influence of the liquids, the frequency domain characteristics of liquid storage structures are different from other kind of structures. In this paper, taking into account the actions of the concrete and rebar in the materials synthetically, the current finite element software ADINA is used to do some 3-D finite element simulation for reinforced concrete rectangular liquid storage structures. The influence of the surface gravity waves upon the liquids, the depth of the liquids, the stiffness of the wainscots and the shape of the structures on the frequency domain characteristics of liquid storage structures with liquid-structure interaction are discussed respectively. This provides the theoretical basis for the research and design of rectangular liquid storage structures.
