中文摘要："內政部建研所於集集大地震後，配合國科會國家地震工程研究中心，負責建築物災害
調查及相關資料的建置，完成初步報告，惟因時間匆促，僅就震害明顯者予以調查統計
。為充分掌握整體面的基本狀況，又於89年2月開始進行蒐集工作。包括118個受災鄉
鎮進行以「戶」為單位的基礎資料蒐集工作，如受災戶的印領清冊、各縣市稅捐單位的
稅捐資料；並已完成各縣市受損建物清冊電子檔匯整、資料正規化及稅捐資料的匯整及
轉碼與部分受損建物空間資料之建置工作。此資料庫應屬九二一震災後最完整的受損建
物基本資料庫，為能發揮此資料庫之最大效益及作為日後相關災害發生時各項預測之功
能，本計畫即以縣市及鄉鎮為單位，以資訊化的方法將資料量化、空間化，並針對不同
因予加以分析統計，使決策單位對此次震災之建物受損狀況能更為清晰及瞭解。
本研究之成果包括建立完整的九二一震害建物毀損資料庫及各類建築物損壞的量化統計
分析與利用地理資料庫進行空間分析展示。由於九二一大地震對於台灣造成的損害相當
嚴重，故藉此研究了解建物結構、建造年代等因子與震害之間的關係及強地動與受損建
物的空間關係，作為其他地區防災預測推估之重要參考依據及相關機制興革之參據。"
英文摘要："Immediately after earthquake, the Architecture and Building Research Institute (ABRI) and National Center for Research on Earthquake Engineering (NCREE) had conducted a building damage survey and related data establishment, then completed a preliminary report. In order to perform a more detail analysis, a more comprehensive has been carried out. A subsidy list of totally and partially collapsed addresses of family were collected and transformed into electronic data. To find out the building inventory (such as structural type, construction period and floor area etc.), we adopted the building tax database as the source and address is used as a key to match the building tax database and the subsidy of severely damaged building database.
These totally and partially collapsed damaged buildings were integrated with GIS platform and electronic map with scale 1:5000. It can also easily integrate with the maps of Che Long Pu fault, soil, geology and terrain in Taiwan and the maps of strong motion distribution of Chi-Chi earthquake. The result of the study included complete damaged building database in Chi-Chi Earthquake, all kind of quantification statistics of building damage, and spatial analysis display by geographic database. Since Chi-Chi Earthquake resulted severely damage in Taiwan, this study could provide not only the relationship between the structural types and construction periods, and earthquake damage, but also the relationship between the strong motion and spatial relation of damaged buildings.
After the development of the GIS-based building damage database, fragility curves of building can be constructed which may be useful for damage assessments early damages estimation systems in Taiwan."
