摘要
将安装于建筑物顶部的水箱设计成为悬吊式水箱,利用水箱中水的振动和水箱摆动耗能来减小建筑结构的地震反应.建立了体系的分析计算模型,并推导出了其动力反应的运动方程;探讨了此装置对建筑结构减震的有效性.并给出了在3条地震波作用下的时程分析结果.表明此装置对结构的相对位移和加速度均有很好的减震效果.
A pendulous water tank is used in the design of a building by fixing the tank on its top. The vibration of water in the tank and the energy exhausted by the swaying of the tank can reduce the seismic responses of the building. An analytical model of the construction with pendulous water tanks is proposed. Based on the dynamic response of the construction, the effectiveness of the pendulous water tank in reducing seismic responses of the construction is discussed. Finally, time-history results under three seismic waves are given, and the control of the responses in both displacement and acceleration of the structure is farily good.
