【摘要】 高柔结构在地震或风荷载作用下会产生很大的振动,本文提出一种控制高柔结构振动的新方法——摆、油阻尼器体系,并在振动台进行了模拟试验。结果表明:该方法可使结构振动位移幅值减小50％。在试验中变换了体系的各有关参数,研究了摆长、质量比、碰击间隙对减振效果的影响。文中详细研究了油阻尼器的工作过程及减振机理,从理论上初步分析了摆、油阻尼器体系减振原因,提出了可供实际设计参考的方法和原则。更多还原

【Abstract】 A new damper system to reduce the lateral vibration of the high rise buildings and towers has been studied. The system mainly uses pendulums and oil dampers. The paper tells how to choose the pendulum length and the damper spring coefficient as well as the impact device. The results of shaking table test show that this system can decrease the building motion by 50%. The mechanism of this system is analysed with details, and suggestion for practical use is also given.更多还原
