地面式钢筋混凝土圆形水池液固耦合模态分析

The modal analyses considering liquid-structure coupling effect of ground reinforced concrete circular tanks

对地面式钢筋混凝土圆形水池进行了考虑液固耦合效应的模态分析,并使用ADINA有限元软件,分析了储液状态、储液高度、水池半径以及液体表面重力波对模态的影响,对比了储液晃动频率的理论和有限元计算结果,推导得到了水池储液晃动基本周期计算公式。

The modal of ground reinforced concrete tanks are analyzed considering liquid-structure coupling effects. The influence of liquid state,liquid height,tank radius and surface gravity waves on modal are analyzed by using ADINA software. And the theory and finite element calculation results of sloshing frequency are compared. And the sloshing foundation period formula of circular reinforced concrete tank is derived.
