摘要
本文着重研究利用悬吊摆作为被动控制装置减小结构地震反应的方法。首选给出具有n个质量摆的单层结构的运动方程,探讨了最佳减震效果的参数范围;然后将该种控制方法应用于微波通讯塔系统,导出了适用于不同减震方案的统一运动方程;最后通过数值计算指出了较有效的减震方案。研究表明,本文提出的方法对于减小结构地震反应是简单、实用和有效的。
This paper is focused on the feasibility of the suspended pendulum used as the passive control device to reduce the structural responses to earthquake ground motion.Frist of all,the single-degree-of-freedom system with the n mass pendulum is given.And then the application of this system to the microwave communication tower is investigated,in which the general equation of motion for different scheme system is presented and the more effective scheme is figured out by a lot of numerical analyses.The study shows that the scheme presented here is applicable to seismic ground motion excitation.
