Abstract
In this paper, a new type of viscoelastic-friction damper which gives damping in large amplitude range has developed. The damper consists of a shear-type viscoelastic damper and a friction damper connected in series. The trial damper was made and the resisting force characteristics were measured, and the parameters of a ten-element rheology model were identified. The frequency responses and seismic responses of a one-degree-of-freedom vibration system supported by the trial damper were measured using a permanent magnetic type shaking table. The experimental results are compared with the calculated results obtained by the FEM software and the effects of vibration suppression of the damper are discussed.
