|
摘要
本文以钢筋混凝土水池为研究对象,采用势流体理论,建立液固耦合分析模型,给出相应的地震反应分析方法.采用上述分析方法对水池结构进行简化,改变水池的各设计参数对水池结构液固体系进行地震反应分析,研究给出考虑液固耦合作用对水池抗震性能的主要影响因素,并总结液体-固体耦合相互作用的规律,为这类钢筋混凝土水池的抗震设计、抗震规范制定和抗震安全性评定提供理论基础和依据.
In this paper,as the object of research,reinforced concreted pool structure is studied by using potential fluid theory.The analysis model for liquid-solid interaction is established,and the method for seismic analysis of pool structure is obtained.Using the analysis method,the pool structure is simplified.With changing the design parameters of reinforced concrete pool structure,the seismic response analysis considering liquid-solid interaction is conducted.The main factors for pool structures considering liquid-solid interaction are studied and obtained.The disciplines of liquid-solid interaction are summarized.Therefore the theoretical principle on seismic design,seismic code,and the seismic safety assessment for the reinforced concrete pool structures is supplied.
