The efficient conversion between building information modeling (BIM) and structural analysis models in steel structures is required. The expression method of the industry foundation classes (IFC) standard was analyzed in this paper and a BIM-based model conversion algorithm for steel structures was developed and applied to the ABAQUS analysis platform. The algorithm can extract the information of structural members, adjust their spatial location, and automatically add analysis data. Based on C# language and the Xbim toolkit, a software was developed and verified by a steel frame, and then applied to the model conversion and structural analysis of Anyang Tourist Transport Center. The results demonstrate that the developed algorithm and software can accurately convert the structural data of steel structures from the design BIM models to the structural analysis models of ABAQUS. Compared to the traditional approach of directly establishing structural analysis models in ABAQUS system, the proposed algorithm can significantly improve the efficiency of structural modeling and analysis for complex structures.
