Vibration control structure of bridge pier
According to the vibration control structure of the bridge pier, the at least two layers of dampers are arranged, the multiple dampers are arranged on each layer, the heights from the dampers on the same layer to the ground are the same, the equivalent modal mass can be the same, and the vibration reduction effect is similar. The heights of the dampers on different layers from the ground are different, the equivalent modal masses are different, and the damping effects are different. The number of the damping mounting frames can be multiple, the heights of the damping mounting frames on different layers from the ground are different, the equivalent modal masses are different, and the damping effects generated by the damping mounting frames are different. Therefore, the equivalent modal mass can be changed by changing the number of the damping mounting frames and the height from each damping mounting frame to the ground, the single vibration reduction effect is avoided, and flexible vibration reduction is achieved.
本发明提供一种桥墩的振动控制结构，桥墩的振动控制结构，设置至少两层的阻尼器，每一层的阻尼器具有多个，且同一层的阻尼器距离地面的高度相同，可以等效模态质量相同，减振效果相近。不同层的阻尼器距离地面的高度不同，等效模态质量不同，减震效果不同。阻尼安装架的数量可以具有多个，不同层的阻尼安装架距离地面的高度不同，等效模态质量不同，各自产生的减震效果不同。由此，可以通过改变阻尼安装架的个数以及各阻尼安装架距离地面的高度来改变等效模态质量，避免减振效果单一，实现灵活减振。
