  • 過去國內外對於黏性阻尼器配置於結構物之常見安裝方式有以下四種: (1)對角斜撐裝置;(2) K型斜撐裝置;(3)上肘型斜撐裝置;(4)下肘型斜撐裝置。然而,因國內近幾年建築師與相關實務工程師基於採光要求,以及為獲得更彈性之建築使用空間,逐漸採用四種國內現行黏性阻尼器與斜撐接合系統,即黏性阻尼器分別與(1)直立鋼構架支撐;(2)減震壁體式構架;(3)鋼筋混凝土支撐墩座;(4)直立式A字型斜撐構架相互銜接。本研究為了解國內現行黏性阻尼器與斜撐接合系統對整體結構減震效益之影響,首先,將針對國內現行黏性阻尼器安裝型式進行完整之探討,其中包含斜撐勁度、上下接合梁之勁度(柔性變形)、阻尼器出力引致之額外彎矩與面外變形所造成減震效益降低。


    The energy dissipation design for building structures resisting earthquake ground motions has been widely accepted as an effective method. Among others, velocity type dampers including viscous dampers, viscoelastic dampers, and oil dampers have been implemented into the seismic design for buildings with various design functions. The installation scheme for viscous dampers worldwide have included diagonal-braced, K-braced and toggle-braced dampers systems. However, in recent practical applications in Taiwan, a few types of installation scheme other than the aforementioned have been adopted for the purposes of increasing the flexibility of space accommodation and/or architectural lighting consideration.
