SAP2000与ABAQUS模型转换软件开发研究

Software development research on model conversion from SAP2000 to ABAQUS

Stoa是一款实现从SAP2000模型转换到ABAQUS模型的数据接口软件。Stoa利用SAP2000软件输出MDB格式的数据库,采用C++语言访问数据库,通过SQL语言查询数据库,提取模型数据,生成ABAQUS建模所需的inp文件,从而实现模型转换,提高ABAQUS软件的建模效率。详细介绍了ADO访问数据库技术、空间杆件单元截面定位、刚性楼板生成、单元配筋以及型钢混凝土构件的生成等软件研制过程中的关键技术。通过对三种模型转化前后效果的比较,验证了Stoa转化模型信息的可行性及准确性,为应用ABAQUS进行弹塑性分析提供了条件。

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.
