摘要
目的:为便于采用通用有限元软件ABAQUS进行结构分析。方法:利用BIM软件中的Revit软件模型数据关联、结构信息完善等优点,解析Revit结构模型中构件的几何信息、物理信息、约束、荷载以及钢筋信息的数据结构,进行Revit-ABAQUS钢筋混凝土结构模型转换的研究。基于Revit API、ABAQUS API,开发RTA-Trans转换程序。结果:将Revit中的结构信息模型转换成ABAQUS中的结构分析CAE模型,并自动对生成的模型进行前处理以及后处理,最后通过实例模型验证该转换程序的可靠性。结论:打通了Revit-ABAQUS模型转换的信息通道,解决了复杂建筑结构在ABAQUS中建模工序繁琐等问题,提高了结构建模以及结构分析的效率,为复杂钢筋混凝土结构的精细化有限元分析提供了可靠依据。
In order to facilitate the use of the general finite element software ABAQUS for structural analysis,this paper uses the advantages of Revit software model data association and structural information improvement in BIM software to analyze the data structure of the geometric information,physical information,constraints,loads and reinforcement information of components in the Revit structural model,and carry out the conversion research of Revit-ABAQUS reinforced concrete structural model.Based on Revit API and ABAQUS API,the RTA-Trans conversion program is developed.The structural information model in Revit is converted into the structural analysis CAE model in ABAQUS,and the generated model is automatically pre-processed and post-processed.Finally,this paper verifies the reliability of the conversion program through an example model.It opens up the information channel of Revit-ABAQUS model conversion,solves the problem of complicated modeling process in ABAQUS for complex building structures,and improves the efficiency of structural modeling and structural analysis,and provides a reliable basis for refined finite element analysis of complex reinforced concrete structures.
