Method of Bridge Structural Analysis Based on Bridge Information Modeling

摘要

Aiming at releasing the potential of BrIM model for improving the efficiency of bridge design and structural analysis, this paper analyzed the combined parametric method of BrIM models and built up structure properties for FEM, thereby established a three-class modeling frame and a new method of bridge analysis based on BrIM. To overcome the gap between BrIM and FEM in bridge structural analysis, the information of bridge structures and special analysis characteristics are set up to establish the reservoir of bridge structure analysis. The mesh controls of the bridge structural information is standardized and preset. The processing generates the corresponding switch file which file type is compatible with a variety of FEM analysis software tools. The seamless transition from BrIM to FEM greatly accelerated the design and analysis of bridges. The smooth parameter flow from the BrIM to FEM is also formed for quick information modification and mechanical analysis of bridge structures.
