[摘要] 本文對比了傳統(tǒng)抗震理論和結(jié)構(gòu)震動理論，介紹了粘彈性阻尼器應(yīng)用于結(jié)構(gòu)的耗能減震。通過分析粘彈性阻尼器的特點(diǎn)、應(yīng)用范圍和原理，推導(dǎo)了相應(yīng)的計算公式。系統(tǒng)地分析了地震作用下結(jié)構(gòu)的動力響應(yīng)。結(jié)果表明：利用粘彈性阻尼器，可以給結(jié)構(gòu)提供附加剛度和阻尼，從而減小結(jié)構(gòu)的動力響應(yīng)，達(dá)到減震的目的。

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.
Keywords: structural vibration control; viscoelastic damper; passive energy dissipation; dynanuc response
