現今常見的震損評估方法主要是依結構物屬性分類，再對各類結構物的樣本之分析結果進行迴歸分析，之後即可查詢以迴歸求得的參數表與公式得到欲評估結構物的近似性能曲線，再以其與需求曲線進行迭代得到震損評估結果，因此結構物分類的詳細程度將影響其結果之準確性，若能以建物之基本屬性資料建立數值分析模型，再透過結構分析得到其結果，將可提昇震損評估結果之準確性，因此本研究提出整合自動建模方法與動態歷時分析之區域震損模擬，其先是以自動建模技術整合校舍資料庫與結構物非線性構件模型元件庫，並搭配使用者對建物及其材料性質進行專業的選擇及設定，即可快速自動產生大量專屬於各個結構物的數值分析模型，再配合使用者上傳的地震歷時資料即可對這些結構物進行動態歷時分析，並將其結果配合運用本研究所建置之自動後處理統計分析程序，求得特定甚至是即時地震下校舍之震損狀況及其構件受震行為等相關資訊，進一步讓震損評估與模擬結果不再只有一個可能造成的損害機率或是指標，而是可以提供更多可輔助決策的資料以供參考，本研究將所提方法自動建模的結果與國震中心對真實結構之詳細側推分析與試驗的結果比較以驗證其準確性，並進一步將其模擬的結果與921集集地震之校舍勘災結果比較以驗證其可靠度，結果顯示本研究所提出之區域震損模擬方法能基於較詳細且個別化的動態歷時分析，提供更詳細且擬真的震損評估與模擬結果。

In a typical seismic damage assessment, structures are classified according to their usage and type, and then structural analysis is performed on all sampled structures of the same group to derive a parametric equation using statistical regression. Parameters for different types of structures can be obtained from reference tables and substituted into this derived formula to obtain the capacity curve of the structure. The capacity curve from statistical regression and the seismic demand curve are iterated to find the damage levels and corresponding probabilities. Its accuracy is affected by the level of detail in classification and the approximation in regression. If models can be constructed based on the basic properties of a structure and their responses can be obtained from structural analysis of these models, the accuracy and details of seismic damage assessment can be improved. This study proposes a new method for regional seismic damage assessment. An automatic modeling method is first developed to construct models of school buildings from a property database and component models. With professionally pre-set settings, detailed regional seismic damage can then be assessed by performing Time History Analysis on automatically generated models. In this manner, more detailed and accurate responses of all school buildings in a region under a specific earthquake can be obtained through numerical simulation based on the time history record of that earthquake. The accuracy and reliability of the proposed method is validated by comparing the base shear - roof displacement curve with data from experimental results and ETABS analysis conducted by the National Center for Research on Earthquake Engineering, as well as data obtained using existing damage assessment methods. Reconnaissance report data on school buildings affected in the Chi-Chi Earthquake is also used for further verification. The proposed regional seismic damage assessment method makes Time History Analysis on individual structures possible to provide a more accurate and detailed damage assessment.
