A Revit-Midas/Civil conversion approach for bridge superstructures analysis

Abstract

In this study, a model conversion method that combined Revit with Midas Civil software was proposed to improve the modeling efficiency and accuracy of finite element calculations for a large bridge structure. The secondary development program was established using the Visual Studio 2022 platform, which was used to convert the model information. A model conversion interface was created by extracting, screening, and then sorting the geometric information of the business information model and generating a Midas Civil Text file. This interface served as a link between Revit and Midas Civil, specifically for the bridge superstructure. The feasibility and reliability of the proposed model conversion method was confirmed using a single-box three-cell Box-girder bridge. The results demonstrated that the model conversion method transfered the Revit model information successfully to a Midas Civil structural analysis model, thereby significantly enhancing the efficiency and accuracy of the finite element modeling of a complex bridge superstructure.
