钢筋混凝土矩形贮液结构的液-固耦合动力分析

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

摘要:

由于液体的影响,贮液结构在地震作用下的动力响应与一般结构不同。本文采用通用有限元软件ADINA,考虑混凝土材料中钢筋的作用,探讨贮存液体表面重力波、壁板刚度、结构尺寸对系统液固耦合动力响应的影响,以及单向、双向和三向地震耦联作用下的液固耦合动力响应。结果为钢筋混凝土矩形贮液结构的液固耦合研究提供了理论依据。

Abstract:

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.
