【摘要】 粘弹性阻尼器是抗震被动控制中一种十分有效的耗能减震装置,本文介绍了粘弹性阻尼器的构造样式及组成材料,建立三种不同阻尼器形式的框架结构,阐述消能支撑的减震工作原理,以时程分析法对装有三种不同形式粘弹性阻尼器框架结构的地震反应进行了分析,对比了中心支撑、偏心支撑与纯框架结构的顶点位移及加速度等。结果表明:设置粘弹性阻尼器中心支撑的混凝土框架结构消能减震效果明显。更多还原

【Abstract】 The viscoelastic damper is a kind of efficient device for suppressing vibration and dissipating energy.The structure style and component materials of viscoelastic dampers have been introduced,three different forms of damper frame structure were established.The principle of shock absorption about the support of energy dissipation is expounded to analysis the earthquake response of three different forms of viscoelastic dampers with time history method.The center support,eccentric support and open frame building frameworks structures,such as vertex acceleration and displacement are analyzed.It is concluded that the effect is obvious to set up center support viscoelastic dampers of the concrete frame structure.更多还原
