摘要
在建築施工過程中,為了避免結構不穩定造成倒塌產生意外,所以針對各施工階段之結
構安全進行分析。當進行分析時,結構分析人員常遭遇到以下問題:(1)結構分析人員會先
閱讀施工計劃書了解整個施工進度,但因施工規劃書難以有效完整表達整個施工過程,使其
解讀困難,沒有發現潛在的結構危險。(2)結構分析人員需要根據施工圖重新建置各階段結
構分析模型,建置過程時間冗長和容易出現錯誤進而影響分析結果。
BIM(Building Information Modeling)為目前發展趨勢,它貫穿整個生命週期,使資訊具
有一致性,避免資訊傳遞遺失;BIM模型內含豐富資訊,如幾何空間資訊、專案資訊、材料
性質或施工順序等資訊。所以擷取BIM模型相關資訊可以進行數量計算、進度模擬、結構分
析等;運用BIM優點解決上述在施工中結構安全性分析過程所遭遇的問題。本文提供一套從
施工進度模擬,到各階段結構分析模型之輸出,期能縮短資訊剖析時間和增加資訊傳遞正確
性,從而減低結構安全性分析之錯誤,供業界參考。
關鍵詞: Building Information Modeling(BIM)、結構安全性分析、施工階段

Abstract
In order to avoid structural failures during construction, engineers conduct structural safety
analyses for each construction stage. Even so, they still frequently meet problems such as: (1)
Structural analysis-related engineers read the construction scheduling plan ahead of time. However,
the plan is not effective enough to express the whole construction process due to the use of paper
documents, therefore the engineers tend to miss potential structural risks. (2) In structural analysis,
the engineers need to rebuild analytical models from 2D shop drawings. This not only takes a lot of
time but also tends to introduce mistakes that affect the analysis results.
Building Information Modeling (BIM) has become a recent trend. It deals with a building’s
complete life cycle, making it easier to maintain information consistency and avoid information
loss. Additionally, there is plentiful information available in BIM models, such as location and
geometric attributes, object properties, construction scheduling, and structural analysis information,
etc. Therefore, the information related to BIM models can be retrieved to implement quantity
calculations, construction scheduling simulations, and structural analyses. In this paper, the authors
describe how, in order to solve the problems mentioned above, BIM was applied to the scope from
construction scheduling simulation to structural safety analyses in each construction stage, so that
information analysis time could be reduced and information could be transferred more accurately,
thereby effectively increasing safety during construction.
Keywords: Building Information Modeling (BIM), structural safety analysis, construction stage
