隨著科技與經濟發展，建築型態逐漸從低矮樓層轉變成中高樓層。鐵路、道路規劃也從平面增加了地下及高架橋梁。然而台灣地處地震帶飽受地震災害影響，向上發展的建築型式面臨振動週期提高、地震危害增加的問題。結構控制技術也隨之發展，各式隔震技術逐步開發並應用於建案中。經過多年研究發展，摩擦型滑動支承已被廣泛應用於結構及橋梁隔震設計。
摩擦型滑動支承具有許多種型式，元件出廠性能測試也已有一套標準測試流程。透過實驗室中振動台，測試檢驗元件性能參數，其中以摩擦係數為此類支承最主要的參數。振動台測試的動態加載方式可以得出動摩擦係數隨速度變化的趨勢，但是對於識別元件滑動瞬間的最大靜摩擦係數較為困難。因而本文透過側推方式加載，針對速度趨近於零、振動台難以測試之元件滑動瞬間設計實驗。
本文實驗使用隔震元件為成功大學歸仁校區複合性災害實驗平台，平台下方裝有共計12個盤式支承墊。利用手動油壓設備於平台南、北兩端靜力側推，分析隔震元件滑動瞬間推力變化以及滑動行為，測試隔震墊於極低速運動性能並識別其摩擦係數。提供工程實務應用於案場現地測試方法，評估隔震元件安裝是否出現瑕疵及元件是否達成預期性能，作為現場驗收參考方式。

With the advancement of technology and economic development, friction type bear-ings have been widely adopted in the design of structures and bridges for seismic isolation. Friction type bearings come in various types, and there is a standardized testing procedure for assessing their performance during the manufacturing process. Performance parameters of these components are tested and inspected using a vibration table. Among these param-eters, the coefficient of friction is the most critical one for such bearings.

The dynamic loading method used in vibration table testing can provide insights into the variation of dynamic friction coefficient with speed. However, identifying the maxi-mum static friction coefficient at the sliding instant of the component proves to be more challenging. Therefore, this study proposes a lateral push loading method to design ex-periments for testing the speed approaches zero, which is difficult to achieve on the vibra-tion table.

In this study, the seismic isolation elements used were the base isolators installed in the Kuei-Jen campus of the National Cheng Kung University. There were a total of 12 pot bearings installed beneath the platform. The experiment involves using a hydraulic system to perform static lateral pushes at the north and south ends of the platform. The goal is to analyze the variation in lateral push force and sliding behavior of the elements, especially focusing on the sliding instant.

By providing practical field testing methods for engineering applications, the re-searchers aimed to evaluate whether there were any flaws in the installation of the ele-ments and whether they achieved the expected performance. This information could then be used as a reference for field acceptance of the installation.
