Seismic Behaviour of Torsionally Coupled Structures Equipped With Viscoelastic Dampers

Abstract

The paper deals with the seismic passive control of torsionally coupled structures, equipped with viscoelastic dampers. Based on the dynamic response of a three degrees of freedom model to a white noise input process, an energy-based design procedure is proposed, and its effectiveness is investigated through an extensive parametric analysis. Subsequently, the proposed methodology is applied to a seven-story torsionally coupled building.
