摘要
将高层建筑结构振动用波动方程描述,当结构顶端设置的控制器成为吸收边界时,它能够尽可能多地吸收行波作为载体而携带的振动能量.文章对均匀连续剪切模型和离散剪切模型分别进行了数值计算,发现适当的结构阻尼能有效地降低施加于结构顶端的控制力,并使得行波控制方法非常适用于高层建筑结构.
The feasibility of a new active control strategy for tall buildings inspired by considertion of the waves travelling within structures is explored. This new strategy is based on adding the control force at the top of the target building to absorb the maximun vibration energy. In this paper the idea is extended to a continious shear bar or a simple discrete system representing tall buildings. It is shown that appropriate increase of the structural damping can reduce considerably the amplitude of the control force at the top of the structure and this makes the control strategy particularly well suitable for tall buildings.
