Research on Method of Distributing Dampers in Structure Installing Viscoelastic Dampers
Abstract:Viscoelastic damper(VED)is a kind of efficient passive control device for suppressing vibration and dissipating energy. The properties of viscoelastic dampers are studied in this paper. According to the seismic performance of existing structures, several methods of distributing viscoelastic dampers are given. Effects of suppressing vibration for different distributions of viscoelastic dampers are compared. A systemic method of seismic design for structures supplemented with viscoelastic dampers is proposed in this paper. Finally, numerical analysis is performed for a ten-story steel frame, several significant conclusions are given.
