顶置水箱对高层建筑地震响应的影响

Influence of Water Tank on Seismic Responses of High Buildings

为了研究顶置水箱对高层建筑结构的自振特性及动力响应的影响 ,在小扰动假设下 ,推导了流 固耦合系统自由振动的控制方程 ,阐述了自振频率和动力响应的计算方法。最后以一个 14层框架结构为例 ,计算了在2种情况下的自振频率及地震响应 ,通过对比 。

To study the influence of water tank on the natural frequencies and dynamic responses to earthquake, the governing equations for the liquid solid coupling system are derived under the small disturbance hypothesis, and the calculation method is described. As an example, the natural frequencies and dynamic responses of a fourteen floor frame structure with and without water tank is calculated. The comparison of the results for the two situations shows effectiveness of water tank as a damper.
