摩擦單擺系統在近年來已經成為熱門的隔震器,並使用在老舊建築的耐震補強、新建橋梁及建築物的隔震等。摩擦單擺系統之行為相當穩定,易於利用理論以及數值分析來預測其行為,而在摩擦單擺系統的分析和設計上,習以靜態遲滯圈的耗能面積來計算摩擦單擺系統的等效黏滯阻尼比。本文將利用外力線性內插法建立摩擦單擺系統的非線性動力分析模式,檢討在各種窄頻、寬頻和規範的地表振動下,等效黏滯阻尼比的制定方式。
In recent years, Friction Pendulum System has become a popular isolator used in seismic reinforcement of the old building, seismic isolation of the new bridge as well as the new building, and so on. Benefited by its behavior stability, behavior of Friction Pendulum System is easy to be predicted by the theory and numerical analysis. However, area of energy dissipated of the hysteresis loop is usually used in calculating the equivalent viscous damping ratio when analyze and design the Friction Pendulum System. This thesis employs the Linear Interpolation of Excitation to establish non-linear dynamic analysis mode of Friction Pendulum System to review the way in setting up equivalent viscous damping ratio under various narrowband, wideband and code ground motion.
