［摘要］Stoa 是一款實現(xiàn)從SAP2000模型轉換到ABAQUS模型的數(shù)據(jù)接口軟件。Stoa利用SAP2000 軟件輸出MDB格式的數(shù)據(jù)庫，采用C++語言訪問數(shù)據(jù)庫，通過SQL語言查詢數(shù)據(jù)庫，提取模型數(shù)據(jù)，生成ABAQUS建模所需的inp文件，從而實現(xiàn)模型轉換，提高ABAQUS軟件的建模效率。詳細介紹了ADO訪問數(shù)據(jù)庫技術、空間桿件單元截面定位、剛性樓板生成、單元配筋以及型鋼混凝土構件的生成等軟件研制過程中的關鍵技術。通過對三種模型轉化前后效果的比較，驗證了Stoa轉化模型信息的可行性及準確性，為應用ABAQUS進行彈塑性分析提供了條件。

Abstract: Stoa is an interface program which can convert software SAP2000 into ABSQUS finite element model. It converts the model information from the MDB format database exported by SAP2000 into the inp format text file which is needed by the ABAQUS, by using Visual C++ programming language to access and SQL language to query. By this way, model conversion from SAP2000 to ABAQUS is realized which can greatly increase the efficiency of ABAQUS preprocessing．Several key technologies including the ADO method to access database, bar cross-section orientation, the generation of the rigid floor, and the generation of reinforcement and SRC are introduced. We compared three typical finite element models which are respectively transformed from SAP2000 to ABAQUS using the Stoa interface program. Comparison of model information before and after the transformation and their corresponding modal analysis results shows the feasibility and accuracy of the developed program Stoa. This work can greatly improve the efficiency of ABAQUS preprocessing and the accuracy of the model transform.
