A NOVEL HYBRID SEMI-ACTIVE TUNED MASS DAMPER FOR LIGHTWEIGHT STEEL STRUCTURAL APPLICATIONS

Abstract

This paper proposes the application of a novel hybrid semi-active vibration absorber for the control of multistorey vibration prone structures under wind excitation. It is shown that the novel device outperforms the traditional tuned mass damper (TMD) by achieving performance gains similar to an active mass damper (AMD) while maintaining robustness at the extra benefit of considerably less energy and actuation demands, satisfying both strict serviceability and sustainability requirements often govern most lightweight steel structural applications.
