台灣為有感地震最頻繁的地區之ㄧ，由於地震具有發生頻率低、影響範圍損失大之巨災特性。因此，在整個地震災害損失中，結構物的損害評估扮演著重要的角色，提供合理且可靠的結構物地震損害評估結果，作為地震巨災風險管理之應用。 地震損害評估中，本文利用非線性動力分析結構物模型，模擬結構物可能損害狀況。地震損害之形成，主因地震反應超出結構物本身之各損害狀況門檻值所致，本研究採用層間變位角為結構物損害狀況判定之主要依據，不同的結構物層間變位角反應，對應不同損害狀況之門檻值，以識別出結構物的損壞程度，並據以建立建築物之易損性曲線，作為後續快速評估建物損害程度之依據。 結構物之地震損害評估為建立各類結構物之易損性曲線(Fragility Curve)，本文針對台灣高雄縣地區鋼筋混凝土典型結構物，以理論分析進行相關研究，研擬典型結構物易損性分析參數，有助於以後評估類似建物在地震作用下，所造成的不同損壞程度和機率，做為將來推估建物補強經濟效益或地震風險管理之參考。 Sensible earthquakes hit Taiwan frequently. An earthquake has catastrophic characteristics of low frequency and devastating disaster. In this case, in the earthquake loss, structure damage assessment plays an important role. Also, this provides reasonable and reliable results of structure earthquake damage assessment to be as applications of earthquake catastrophe risk management. In the earthquake damage assessment, this article applies nonlinear dynamic analysis structure model to stimulate the structure possible damage condition. The main cause of forming earthquake damage is that dynamic response exceeds in structure itself damaging threshold. Therefore, story drift ratio is adopted to determine damage state of building. damage state could be identified with different drift ratio. This will help to assess buildings damage rapidly according to establish fragility curve of building. The seismic structure damage appraisal is to establish all kinds of structure fragility curve, this article aim to do researches on typical reinforced concrete via theoretical analysis method and determine typical structure vulnerability analysis parameters in Kaohsiung County areas. This will help to assess similar buildings under earthquake which causes different damage state and probability as well as to evaluate the economic benefit of building retrofitting or reference of earthquake risk management in the future.
