摘要
介绍了向心式变摩擦阻尼器的原理及其基本力学性能，探讨了安装向心式变摩擦阻尼器结构在自由振动和强迫振动时的动力特性和动力反应特点，揭示了向心式变摩擦阻尼器引起结构抖振的机理，对安装向心式变摩擦阻尼器的结构的地震反应进行了分析，研究了向心式变摩擦阻尼器的参数对结构动力特性及地震反应的影响，给出了受控结构的非线性反应谱。
The Energy Dissipating Restraint (EDR) is a passive friction device that is behaviorally sophisticated but mechanically simple.. The characteristics of this device are strong self-centering ability and linear restoring force-displacement relationship. The EDR can produce various hysteresis loops, however, this paper mainly investigated the performance of triangular shaped hysteresis loops. The performance and mechanism of EDR are introduced. The oscillation characteristic of structures with EDR under fr...
