| 摘要: | 建築物結構受地震力作用產生之地震反應為耐震工程反應控制技術評估指標之一，裝設或未裝設隔震之效能比較，為業界普遍關心之議題，地震反應控制評估目前係仰賴電腦程式ETABS分析，非短期內可比較出其結果，因此如何以簡單迅速之計算方法評估隔震建築物對於地震反應之優勢，促成本研究之動機。
本研究以耐震設計規範最小設計地震力為基礎，選擇臺北盆地區高中低層三種不同規模建築物，模擬分析裝設與未裝設隔震之地震反應效益，此效益包括建築物頂層位移、底層剪力、結構振動週期、層間相對位移角、頂層加速度五項地震反應因子。
研究顯示，高層隔震建築物電腦ETABS分析法之地震反應，以層間相對側向位移角之效能最為顯注，其次以結構振動週期為優先考慮之因子，頂層位移次之，之後順序為頂層加速度與底層剪力；簡易分析法之地震反應，則以底層剪力之效能最為顯注，其次以頂層加速度為優先考慮之因子，頂層位移次之，之後順序為層間相對側向位移角與結構振動週期。

Seismic response analysis of buildings is the evaluation indicators for the seismic response control technology in structure seismic resistant analysis. Compare the performance of building with or without seismic isolation, as issues of common concern to the building industry, the seismic response control system relies on a structural analysis computer program ETABS, The results comparison are not obtain in short-term, and therefore how quickly a simplified calculation methods to assess the seismic response analysis of buildings to facilitate the research motivation。
In this study, seismic resistant design specifications based on minimum design seismic forces, select the Taipei basin area in three different scale buildings, such as High-rise building、medium-rise building and low-rise building. With or without seismic isolation of reaction efficiency, the benefits include building the roof displacement, the base shear, structural period, the relative rotational angle between floor, the roof seismic acceleration response factor.
Research results show that high-rise isolated building seismic response analysis method of building computer program ETABS to performance relative lateral rotation angle between layers of the most significant note, followed by the period of structural vibration factor priority, the roof displacement, followed by the top of the order after the acceleration with the base shear; simplified analysis of seismic response, then the performance of the underlying shear of the most significant note, followed by acceleration in the top priority of the factors, the top displacement followed after the order relative lateral rotation angle between layers and structural period.
Medium-rise isolated building seismic response analysis method of building computer program ETABS to performance relative lateral rotation angle between layers of the most significant note, followed by the period of structures, the roof displacement followed, by the roof and base shear acceleration; simplified analysis of seismic response, then the performance of the most significant structural period injection, followed by the roof displacement, lateral rotation angle between layers, followed by the top order after acceleration and base shear.
Lower-rise isolated building seismic response analysis method of building computer program ETABS to performance relative lateral rotation angle between layers of the most significant note, followed by the period of structures, the roof displacement followed, after the order of the roof and base shear acceleration; simplified analysis of seismic response, then the performance of the roof most significant displacement injection, followed by a relative lateral rotation angle between layers, structural period followed after the top order and the underlying shear acceleration. |
