Abstract
Viscoelastic damper dissipates energy through shear deformation of the viscoelastic material, and it causes temperature rise resulting softening of the material under long duration loading. This paper discusses properties of a full-scale viscoelastic damper during long duration wind-induced vibration and presents the simplified evaluation method. In addition, we propose a new analytical model which is considering heat transfer effects. Good accuracies of this analytical model is demonstrated by comparing with results of the long duration loading test.
