傳統定阻尼式的滾動隔震支承，可能為了避免在少數大型地震下的位移反應超過設計位移而產生碰撞，而保守設計阻尼力，導致滾動隔震支承的加速度反應於一般地震下過度放大。本研究開發智慧型滾動隔震支承，嘗試將壓電致動器安裝於滾動隔震支承內，使滾動隔震支承具備可變式阻尼的功能。另一方面，若能於地震的初達波到達後的數秒內，利用現地型地震預警的技術，根據初達波特徵推估該次地震可能造成的最大位移反應，即可針對該次地震調整適當的阻尼，使小地震時阻尼小、加速度反應小，但大地震時阻尼大、加速度反應大，但是不至於發生碰撞。為達此一目的，首先必須瞭解何種特性的地震會使得最大位移反應過大。根據前人研究，傳統之設計反應譜之相關參數推估位移反應之變異性過大，猜測其主要原因為斜面式滾動隔震支承並無所謂的勁度與自然週期。因此本研究探討各種地震特性參數對於最大隔震支承位移反應的影響，尋找造成斜面式滾動隔震支承之最大位移變異性較低的參數，並提出可根據該參數控制滾動隔震支承之阻尼的控制方程式。在假設現地型強震預警技術可以準確預測該地震參數的條件下，即可根據所預測之該地震參數，控制壓電致動器增加阻尼力，並探討對於最大位移及加速度反應之控制效果。

In order to avoid collisions due to the displacement reaction exceeding the design displacement during some large earthquakes, the damping force of the rolling isolation support may be conservatively designed, resulting in the acceleration response being over-amplified during the general earthquakes. This research attempts to mount the piezoelectric actuator in the rolling isolation support, so that the rolling isolation support has the function of variable damping. On the other hand, if it is possible to estimate the maximum displacement response that may be caused by the coming earthquake based on the characteristics of the primary wave, within a few seconds after the arrival of the seismic wave, the damping can be adjusted for the coming earthquake. In order to achieve this goal, it is first necessary to understand which characteristics of the earthquake will cause the maximum displacement response to be too large. This study investigates the influence of various seismic parameters on the maximum displacement response of the isolation support, and proposes to control the damping of the rolling isolation support according to these parameters. Under the assumption that the earthquake early warning technology can accurately predict these seismic parameters, the piezoelectric actuator can be controlled to increase the damping force according to the predicted seismic parameters, and the control effect on the maximum displacement and acceleration response is studied.
