[提要] 介绍了高烈度区某12层综合办公楼采用粘滞阻尼器的消能减震设计。设计中,在结构原拟设剪力墙的位置设置单斜撑粘滞阻尼器消能支撑,所采用的粘滞阻尼器为具有自主知识产权的速度线性相关型粘滞阻尼器。时程分析结果表明,粘滞阻尼器可大量耗散地震动能量,有效降低结构在地震作用下的振动反应。
[关键词] 框架结构 粘滞阻尼器 消能减震The vibration energy dissipation design of a 12-storey structure with fluid viscous dampers in high seismic fortification intensity site is introduced. The shearwalls designed at first were replaced by diagonal dissipating energy braces with fluid viscous dampers. The damper is a kind of velocity related damper without rigidity. The relationship between the damping force and the velocity is similarly linear. Dynamical analysis results prove that the fluid viscous dampers effectively dissipate the structural vibration energy and reduce the vibration response induced by earthquake.
