Model Conversion and Application Framework for Rectangular Aqueduct Superstructures: Integrating Revit and Midas Civil

To improve the modeling efficiency of finite element analysis models for rectangular aqueducts based on the BIM information model, this study proposes a model conversion method that integrates Revit software and Midas Civil. By accessing the attribute information stored in the structural component objects of the BIM model, the finite element modeling parameters required for structural analysis are obtained. A secondary development program has been established using the C# programming language on the Visual Studio 2022 platform, resulting in the creation of a model interface program (Revit-Midas Civil) that facilitates the conversion of model information. This has saved designers time in constructing finite element models. The feasibility and reliability of the proposed model conversion method have been validated through a multi-girder rectangular aqueduct. The results indicate that the model conversion method successfully transformed structural analysis model information from Midas Civil into Revit model information, significantly enhancing the modeling efficiency and accuracy of rectangular aqueduct structures.
