摘要

开发研制了圆筒式粘弹性阻尼器,从振动控制的角度出发,通过试验,探讨了其力学性能随环境温度、激振频率、变形幅值和滞回圈数等因素的变化规律;结合实际工程,给出了工程结构安装了圆筒式粘弹性阻尼器后的地震反应计算方法和主要计算结果,计算表明,结构安装粘弹性阻尼器后,层间位移和加速度较原结构减小明显。
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.
