In order to better make the conversion interface between Revit and ANSYS software suitable for structural analysis of longspan complex bridges such as cablestayed bridges, based on Revit 2019 and Revit API technology, the BIM model of the cablestayed bridge was transformed into an ANSYS finite element model with different element types by using C# language for secondary development. Among them, the main beams, piers and supports were transformed into solid elements, and the stay cables were transformed into rod elements. And through graphical user interface (GUI) development and database development, meshing, applying constraints, applying loads, solving and postprocessing operations were directly performed based on the Revit model. The transformation from BIM model to ANSYS finite element model and the automation of structural static analysis were realized, and the main bridge of Changshan bridge was taken as an example to verify. The results show that this method can realize the accurate conversion between BIM model and different element finite element models. Through the GUI interface and the operation of the Revit model, the bridge designers can more quickly and effectively carry out the structural stress analysis, which lays the foundation for improving the work efficiency and information level of the bridge industry.
