【摘要】 基于国内某大型水利工程进水塔结构,采用ADINA大型结构分析软件,利用其势流体单元模拟水体,构建了塔体—地基—水体三维非线性流固耦合有限元分析模型,分析了进水塔塔顶排架结构及塔体自振特性、地震反应,研究了塔顶排架结构对进水塔动力响应的影响,结果可为进水塔结构的抗震设计提供参考。更多还原

【Abstract】 Based on the intake tower of a large-scale hydraulic engineering in China,the structure analysis software ADINA is adopted to establish three-dimensional nonlinear finite element model of tower-water body-foundation fluid solid coupling by simulating water body with potential flow element.Then it analyzes the natural dynamic characteristics and dynamic responses of the intake tower and its upper bent structures.Finally,the influence of the upper bent structures of intake tower on its dynamic responses is studied.The results can provide reference for seismic design of intake towers.更多还原
