摘要
于抗弯矩构架之钢骨大楼内设置流体黏滞性阻尼组件(Fluid Viscous Dampers,简称FVD),不仅可以降低结构体基底剪力,同时亦可减少结构体楼层位移、加速度以及层间侧向位移角(Story Drift)等各项反应。这些反应系衡量建筑物摇晃程度、地震力输入能量以及结构体或非结构体损害之重要指针。本文针对钢骨大楼内加装FVD,以两栋地上九层,地下三层钢骨大楼为例,说明抗弯矩构架內,以线性FVD提供了大约10％的总阻尼比后,大楼在加速度历时作用下之各项反应;文中亦说明阻尼组件之配置、阻尼力、阻尼常数以及冲程之选择,同时亦讨论到采用FVD之效益。
The application of the Fluid Viscous Dampers (FVD) in high - rise steel building structures could reduce not only the structural shear force, but also the storey displacement, accelerate and the story drift. These reaction data are important signatures to the anti - seismic performance of the buildings. This paper present two design examples which put FVD into use. As FVD offer 10% damp ratio, these two buildings, which are 9 -stories on ground and 3 - stories underground, show an ideal performance in -structural reaction. This paper also illustrates the disposition of the damp apparatus, the damp force, and the damp parameter. The economic benefit is also discussed in this article.
