摘要
本文通过水箱的正弦波激振试验,验证了计算振荡水频率的理论公式,得出了估算振荡水阻尼的经验关系。文中通过水箱-结构体系的地震模拟试验,验证了水箱减振装置的控制效果,并结合试验结果,对水箱-结构体系的地震反应进行了数值模拟。研究结果表明,利用水箱减小高柔结构的地震反应是一种简易、可行、有效的被动控制方式。
The dynamic characters of TSD (Tuned Sloshing Damper) are determined by means of the sinusoidal wave scanning tests. The theoretical formula for calculating the nature frequency of TSD is tested and verified. An experimental relation for estimating the damping ratio of TSD is obtained by a regression of experimental data. Seismic modeling tests and numerical analyses of the structure-TSD system are carried out and the results show that TSD is an effective,simple and easy passive control measure for reducing seismic responses of flexible, structures.
