中文摘要 | 本研究在探討高架水塔之易損曲線,水塔之結構係頭重腳輕之構造物,輸入地震水平加速度,以SAP200NL進行分析非線性歷時動力分析,並考慮高架水塔之工址離斷層距離之遠近及土壤性質所造成影響,並以水塔破壞之型式及破壞機率,進行易損性分析。 本研究係以科學園區之3000噸高架水塔及自來水場之300噸高架水塔,作為研究之案例探討,考慮在921地震及331地震模擬下,分別評估不同程度損害及發生機率百分比建立易損曲線。 輸入地震時考慮堅實地盤、普通地盤、軟弱地盤及臺北盆地等四種地盤,藉以了解輸入地震之變異性,藉此建立高架水塔之易損曲線,提供補強防災設計規劃之應。 |
英文摘要 | The elevated water tanks play an important role in the science industrial park in Taiwan. The damage of this water tanks leads to a severe impact in the high-tech science industrial parks. The objective of this research is to construct the fragility curves of elevated water tanks situated on the various site soil conditions. Two elevated water tanks with 300tf and 3000tf capacity serve as two representative structures to conduct a rigorous nonlinear time history analysis. A nonlinear time history analysis is performed with the 1999 Chi-Chi earthquake and the 2002 Hualien earthquake on the various site to account for the effect of variation of input ground excitation. The filled water tanks with different capacity are performed to identify the different failure modes and to construct the corresponding fragility curves. |
