[摘要] 本文对比了传统抗震理论和结构震动理论，介绍了粘弹性阻尼器应用于结构的耗能减震。通过分析粘弹性阻尼器的特点、应用范围和原理，推导了相应的计算公式。系统地分析了地震作用下结构的动力响应。结果表明：利用粘弹性阻尼器，可以给结构提供附加刚度和阻尼，从而减小结构的动力响应，达到减震的目的。

Abstract: In contrast with the traditional shock-isolation theory and structural vibration theory, the viscoelastic damper which is applied to the energy suspension of structure was introduced. Through analyzing the characteristic, application and principle of viscoelastic damper, the corresponding formulas was deduced and the earthquake effect of the structure under dynamic response was analyzed. Results show that using viscoelastic damper, additional stiffness and damping to structure can be provided. Thus, the dynamic response and shock of structure can be reduce.
