Explore the application of bim binding with abaqus in bridges

Abstract

Intelligent construction is of great significance to civil engineering, in which BIM modeling technology can greatly improve the efficiency of construction design. However, this technology is still lacking in the field of bridges. Therefore, this paper will explore how to use BIM technology in the field of bridges to improve the efficiency of bridge construction and reduce the construction difficulty. This paper takes Nanping Minjiang Bridge as a model, establishes the bridge model with BIM software and analyzes the model with finite element analysis software abaqus, analyzes the force of the bridge main girder with spatial finite element method and analyzes the construction process, which will provide some reference for the future construction. The experimental results show that by exporting the Revit model to SAT format, the model can be directly imported into Abaqus for the corresponding analysis, thus avoiding the secondary modeling, saving the design time and improving the modeling efficiency. In the preconstruction phase of the bridge, the BIM model can deepen the understanding of the designers and constructors of the project, clarify the internal distribution of components, and accurately calculate the most dangerous areas of stress. This process not only ensures construction safety but also provides important support for engineering inspection after the bridge is completed.
