摩擦單擺支承(簡稱FPS)為現今許多結構物常採用之隔震元件，若需觀察或測試實尺寸結構裝設FPS之實際消能行為或隔震效果，多透過縮尺結構模型搭配縮尺元件之振動台實驗完成，然而縮尺元件之消能行為是否足以推論實尺元件之隔減震效能，可進一步採用實尺寸元件之擬動態實驗進行測試。但要實行擬動態實驗前，需先確認FPS元件之摩擦力回授訊號量測值是否會受到加載速率之影響。因此本文採用多重取樣技術，針對FPS系統進行不同加載速率之元件測試，並針對摩擦力量測訊號進行探討。傳統之元件測試試驗命令發送時間間隔通常等於量測取樣時間，而多重取樣量測技術可以在制動器位移命令發送時間間隔中，利用較多的量測取樣數目，以了解致動器的詳細運作過程及試體的行為，並可藉由較多的量測取樣資料進行訊號之平均，以獲得較準確之摩擦力回饋訊號，確保未來擬動態實驗之正確性。且經由不同加載速率之測試，亦可選擇在對應試體載重下，油壓制動器工作範圍之合適命令發送時間間隔，以確保制動器位移命令之達成率。多重取樣元件測試結果顯示，在致動器的工作範圍下，多重取樣元件測試之加載速率快慢並不影響摩擦力回授訊號量測值，證實FPS的確可以施行慢速擬動態實驗。而初步擬動態實驗測試結果顯示，令實驗結果不盡理想的主因可能在於本實驗架構無法完整模擬摩擦力的黏著行為，未來若能改進此情況則擬動態實驗可有成功的機會。

Friction pendulum system (FPS) is widely adopted isolation component for many structures today. In order to observe or validate its energy dissipation behavior and isolation performance, shaking table tests of scale-down models and scale-down components are usually conducted. The experimental results may not be able to infer the isolation performance of full-scale components; therefore, pseudo-dynamic tests of full-scale components can provide further information. Prior to the pseudo-dynamic test, one should confirm that the friction behavior of FPS is loading rate independent. The multiple sampling technique is applied in this study to observe the hysteresis loops of FPS components under different loading rates. It samples multiple feedback measurements during the sampling period of actuator command to provide detailed characteristics of FPS components and ensure the quality of force measurements. Furthermore, multiple sampling data can be averaged to ensure the accuracy of pseudo-dynamic test. The results of component tests demonstrate that the hysteresis loops of FPS components under different loading rates have similar rate-independent characteristics.
