BIM為基礎之建築物耐震能力詳細評估自動化作業模式
BIM-BASED AUTOMATION PROCESS FOR SEISMIC DETAILED ASSESSMENT OF REINFORCED CONCRETE BUILDING STRUCTURE
摘要
本文以結構工程師觀點，提出以BIM為主之建築物耐震能力詳細評估自動化流程。目前的建築物耐震能力評估作業，須由建築師、土木或結構技師執行，圖資與模型管理不易，尤其當原始竣工圖或是結構設計圖資訊的人為輸入錯誤時，更是難以查核錯誤。評估補強所用之結構分析模型，也未轉換為建築資訊模型，無法提供後續營運維護管理使用，甚為可惜。因此，本研究發展自動化流程，嘗試整合建築師、技師與業主所期待功能。首先，建立建築模型資訊模型，並經由自行開發介面處理程式獲取耐震評估分析主要參數，再匯出至結構分析程式。最後完成塑鉸設定及非線性靜力側推分析，即可快速且正確的求得建築物的耐震能力。工具之選用，建築模型資訊模型為TEKLA Structure，優點為梁、柱鋼筋由API輔助程式快速佈設；耐震能力評估程式，使用國內經營建署認可之TEASPA或SERCB程式；結構分析程式為建築結構主流分析程式ETABS。由TEKLA Structure匯出文字輸入檔供TEASPA或SERCB計算塑鉸性質，則由本研究自行開發程式來串接。本研究最終以一棟新建及一棟既有結構進行案例展示，優點為資訊保留在TEKLA Structure中，以利資料之管理與保存。此外，降低分析時間及資訊在交換的過程中之遺漏，而能快速且正確的求得建築物的耐震能力。

This paper proposes an automation process for BIM-Based detailed seismic assessment of buildings based on BIM, from the structural engineering point of view. The current building seismic assessment tasks must be performed by architects, civil engineers, or structural technicians. It is not easy to manage drawings and models, especially when the original as-built drawings or structural design drawing information is entered incorrectly by humans, it is even more difficult to check errors. It is a pity that the structural analysis model used in the assessment of reinforcement has not been converted into a building information model, and cannot be used for subsequent operation and maintenance management. Therefore, this research develops automated processes and attempts to integrate the functions expected by architects, technicians and owners. First, establish the building model information model, and obtain the main parameters of seismic evaluation analysis through the self-developed interface processing program, and then export it to the structural analysis program. Finally, assigning the plastic hinges and carrying out the nonlinear static pushover analysis, the seismic resistance of the building can be quickly and accurately obtained. The building model information model used in this study is TEKLA Structure. The advantage of applying the Tekla Structures is to figure out the beams and column reinforcements by self-developed API programs. The seismic assessment programs are TEASPA and SERCB program, and structural analysis program is ETABS. The text input file exported by TEKLA Structure for TEASPA or SERCB to calculate the properties of plastic hinges will be connected by a program developed by authors. This research finally uses a new-design building and an existing structure to demonstrate the case study. The advantage is that the information is reserved in the TEKLA Structure to facilitate the management and preservation of the data. In addition, the analysis time and the omission of information in the exchange process are reduced, and the earthquake resistance of the building can be quickly and accurately obtained.
