Mechanical Analysis of a New Viscoelastic Damper under Earthquake Damage

The viscoelastic damper is a kind of effective passive energy-dissipating device.The mechanical property of ordinary viscoelastic damper is affected by environmental temperature,incentive frequency and strain amplitude and may produce deviation to the results of structural design.This paper introduce a new viscoelastic damping material,whose mechanical property are unaffected by environmental temperature and incentive frequency.The dynamic mechanical property of new viscoelastic dampers adopting the new viscoelastic damping material and that of ordinary viscoelastic damper are contrasted.Our study shows that the results of the energy-dissipating and shock-absorbing structure adopting the new viscoelastic damper as energy components is more accurate and efficient.
