Exploring the Application of Building Information Modeling in Finite Element Analysis Research

Abstract

Due to the increasing complexity of recent bridge structures, the traditional approach of finite element analysis based on design drawings appears to be inefficient. The creation of fine and complex assembly models in finite element analysis software is often cumbersome and does not allow the use of data-based methods to model the design in real projects. Based on Building Information Modeling (BIM) and Revit secondary development technology, an automatic conversion of BIM to finite element mesh modeling system was developed for rapid analysis of detailed structural condition, design warning and secondary construction feasibility study. A better adapted hexahedral meshing algorithm based on the mesh method is used to cope with complex geometric features through the study of the recognizable syntax of the finite element analysis software and the interfaces exposed by Revit. In addition, the asymmetric arch bridge project confirmed the effectiveness of the method. The results of the cases show that the component models are accurately positioned and the model data information can be fully transformed. In addition, the labor to build the analytical model is reduced and the accuracy of the finite element analysis is maintained. The method proposed in this paper realizes the purpose of rapid analysis with BIM as the pre-processing and finite element analysis as the post-processing, which provides a new idea for the accurate assembly of the model and the structural analysis of the secondary construction.
