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.
