    摘要: 台灣處於地震發生頻繁的環太平洋地震帶,為世界上發生有感地震最頻繁地區之ㄧ,也由於地震災害發生嚴重影響了我們的生命財產,因此在地震災害的損失評估中,結構物的損失評估佔了重要之地位。為了提供一合理可靠的結構物損失評估結果,需建立出結構物之地震易損性曲線,本文將依據不同時期之建築物耐震設計規範,建構出適合各時期規範之不同樓層鋼筋混凝土結構物分析模型,再利用SAP2000進行非線性動力歷時分析,模擬結構物受震後之真實反應,並定義分析所得之結構物最大層間變位角為損害參數,依照損害參數所對應不同損害狀態之門檻值,以識別出結構物的損害程度。 當建立出可信之鋼筋混凝土結構物地震易損性曲線後,於地震災害發生前,即可針對不同時期所建之鋼筋混凝土結構物,進行受震後之損害狀態預測,依照其不同之損害情形訂定合理的風險管理機制;於地震災害發生後,可快速提供損害評估結果給相關單位於第一時間進行防、救災參考依據。 Taiwan locates on high seismicity pacific ring of fire. It is also one of high felt earthquake occurring zone. Due to earthquakes cause damages to life and properties, damage assessment of structures is the most important part of earthquake loss assessment. For providing a rational and reliable result of structural loss, fragility curves of structures must be established. In this thesis, finite element models for vary floors of RC structures of different building code phase are modeled. SAP2000 is utilized to perform non-linear dynamic analyses. Responses of structures when earthquakes occur are simulated. Maximum story drift of each simulation result is defined as the damage parameter. Damage state of structure can be identified through damage parameter which is correspondent to threshold of damage state. After establishments of reliable seismic fragility curves of RC structures, damage assessment of structures of building code decade can be performed to predict losses after earthquakes happening. Risk management mechanisms can be set up via assessment above. After a real earthquake happening, quick assessment can be performed, and result of assessment could be a guide to prevention and rescue of earthquake hazard.
