建築資訊模型於RC建築物耐久性能診斷與維護管理階段之應用

Study of Building Information Modeling Applied in Durability Assessment and Maintenance Management for RC Buildings

近年來，鋼筋混凝土建築物在生命週期中維護管理日益受到重視，除透過量化的耐久性能診斷，給予建築物最適當的補修維護，藉以提升耐久性能的不足，並將耐久性能診斷納入整體營建管理體系。現階段診斷結果的紀錄仍然採用以往傳統的文字表格紀錄，因缺乏生命週期資料建檔，致使許多相關文件因年代久遠不易保存而遺失，造成資料分析不易、保存困難之問題。因此本研究提出維護管理模式資訊化，藉由建立一套耐久性能診斷與維護管理系統，並採用資料庫儲存所有診斷資訊，建立多個分析模組提供系統自動資料處理功能，使用者介面提供診斷資訊查詢，並把相關圖說、維護策略及診斷手冊等文件做整合，協助人員日後進行建物診斷之資料追蹤；此外，本研究亦將此系統結合建築資訊模型(Building Information Modeling, BIM)，透過3D模型系統解決傳統2D圖面不夠直觀之問題，更將診斷結果以視覺化方式呈現於模型，3D圖形模式可供快速查詢相關資訊，進而提升診斷人員執行建築物維護的作業效率。

Reinforced concrete (RC) buildings deteriorate over time; consequently, maintenance strategies for their serviceability and safety should be arranged in accordance with their life-cycles. In addition to assessing the durability of an RC building, an appropriate maintenance strategy can be used to prolong its service life or maintain its serviceability and safety. However, the assessment method of an RC building’s durability uses paper documents to record the related assessment information, and the information is not easy to maintain as time goes by. Therefore, this study proposes durability assessment and maintenance system that consists of several modules for auto-processing the information, including integrating and search functions. Additionally, the proposed system is connected to Building Information Modeling (BIM) to visualize the assessment data. Furthermore, by making use of the quantitative index of durability obtained from the detailed assessment, an appropriate maintenance strategy can be suggested to prolong the building’s service life. The proposed system also suggests maintenance strategies corresponding to various deterioration causes and degrees. Finally, a case study is used to investigate the application of the system proposed in this paper.
