| Abstract: | A type of circular-viscoelastic damper is developed and tested. Based on the vibration control theory and the test results, the effects of environment temperature, exciting frequency, strain magnitude and hysteretic time on the mechanical properties of circular-viscoelastic damper are quantitatively discussed. Considering the practical engineering structure, the seismic design of viscoelastic dampers and energy-dissipated braces is illustrated. The calculation method of earthquake response with the main result is presented, which shows that circular-viscoelastic damper can significantly reduce the displacement and acceleration responses between stories of the structure. |
| Keywords: | circular-viscoelastic damper mechanical property earthquake response |
