摘要:	建築資訊模型(Building Information Modeling, BIM)的使用在現今業界中越來越廣泛，且更為頻繁的使用，但BIM軟體的結構分析能力目前仍不足以取代傳統習慣使用的結構分析軟體，因此本研究計畫利用BIM軟體進行建模後，將模型資訊導入至業界常用之結構分析軟體中，進行結構分析並取得最佳化斷面設計的資訊，最後將最佳化斷面的結果匯回BIM軟體之中，並且更新BIM模型之中的梁柱尺寸，以達到最節省施工材料並且整合BIM軟體與結構分析軟體的目的。由於業界常用之BIM軟體大多以Autodesk公司所推出的Revit以及Trimble公司收購的Tekla作為最常用之建模軟體，而其中Revit相較於Tekla具備更高的整合性，包含結構、機電等。因此本研究為能夠整合更多方面之建築資訊，採用Revit作為主要建模軟體。結構分析軟體在業界大多使用CSI公司所推出之ETABS以及SAP2000進行結構計算，其中ETABS多使用在建築上，而SAP2000能夠在較不規則的造型中使用，因此為後續不局限於建築方面，故採用自由度較高之SAP2000進行。本研究之成果可完整將線性構件模型由Revit轉換至SAP2000中，並確實將SAP2000中最佳化分析設計後的斷面尺寸資訊匯出，讀取最佳化設計之參數後，修改Revit模型。;Building Information Modeling (BIM) is widely used in practice nowadays, however the structural analysis capabilities of BIM software are still not sufficient enough to replace the traditional software. As a result, this study utilizes BIM to conduct modularization and import the result of modularization from BIM into the traditional structural analysis software for the information of optimized cross-sections. Finally, we import the results of the optimized cross-sections back to BIM software and renew the sizes of pillars to match the objectives that can both save raw materials and integrate BIM with the traditional structural analysis software. There are two kinds of the most widely-used BIM software in the industry as modularizing software, which are Revit, introduced by Autodesk, and Tekla that was acquired by Trimble. Specifically, Revit has better integration than Tekla in terms of structures and mechanics. Therefore, this study selects Revit as the primary modularizing software for the ability to integrate more aspects of building information. For the structural analysis software, ETABS, introduced by CSI, and SAP200 are more frequently used in the industry. In comparison, ETABS is more applied to buildings, and SAP2000 can be used in less symmetric scenario. In order not to be limited in building applications in the following research, we choose SAP200 for higher flexibility. The results of this study can completely transform the linear component model from Revit to SAP2000 and the information of the sizes of cross-sections after the optimization can be completely extracted from SAP2000 that is able to read the parameters of the optimized design and modify the Revit model.
