Abstract:	本研究蒐集921集集地震所紀錄之強地動資料以及建築物損害資料庫和人員罹難資料庫，利用「等震度」與「等母體數」之概念，建立建築物易損曲線及人員罹難曲線，更進一步求得建築物損害率D值與人員罹難率M值兩者間之關係。利用等震度區間使得建築物損害率與人員罹難率能於相同PGA基準下進行比較以得到兩者之間關係，並且探討其影響因素：(1)等母體數類型、(2)等母體數大小以及(3)不同類型建築物。地震災情程度因建築物類型之不同而造成損害程度不同，因此如何分配震災資源於不同建築物類型亦是減災之重要步驟，故本研究亦對不同類型建築物損害率與人員罹難率兩者間之關係進行探討。本研究發現於所得到之關係圖上出現偏高之異常數據點，由於異常數據點應該是基於地震所發生之特定區域而產生，故探討異常數據點並且考慮是否應將其加以刪除，而得較具有合理性之建築物損害率與人員罹難率關係式，期待未來可快速分析災情以達到減災之效能。 In this research we collect the murdered people damage data, the damaged buildings data and the strong motion data of the Chi-Chi earthquake, and propose the concept of “iso-seismic intensity” and “equal intervals”. We can construct fragility curves and mortality curves, and furthermore derive the relationship of buildings damage rate, D and people mortality rate, M. We employ the intervals of iso-seismic intensity to derive the relationship of buildings damage rate and people mortality rate in the same PGA base, and discuss the influential factors which are (1) the type of equal intervals, (2) the magnitude of equal intervals, and (3) the different types of buildings. We also discuss the relationship of buildings damage rate and people mortality rate in different types of buildings because the degree of earthquake disaster will be different in different types of buildings to be an important step in decreasing disaster. In this research we find the exceptional data in the relationship of buildings damage rate and people mortality rate. Due to the exceptional data are resulted from the specific area and discuss that the exceptional data whether should be deleted to get reasonable relationship of buildings damage rate and people mortality rate for expecting to analyze earthquake disaster quickly and get the effect of decreasing disaster.
