内容記述
Viscoelastic damper dissipates energy through shear deformation of the viscoelastic material, and it causes temperature rise resulting softening of the material under long duration sinusoidal and wind-incused excitation. This paper discusses properties of viscoelastic damper during long duration loading. In addition, the two analysis methods and simplified evaluation method using sinusoidal-wave as a substitute to random time history data properties are presented in this paper. Accuracy of these analysis methods and the evaluation method are validated by comparing the long duration loading tests.
