In response to the current issues of low standardization and structuring of attribute data in bridge information models,as well as poor usability and scalability,this study investigates a classification method for bridge information model attributes and explores the principles of component code in bridge information models.Based on geometric and non⁃geometric attribute interface files,a method for constructing component attributes in bridge information models is proposed.Practical application suggests that the bridge information model coding method should account for the functional hierarchical structure and spatial composition of components.This approach generates a unique code for each component in the project,laying a foundation for model management in data construction.The proposed classification method for bridge information model attributes can enhance the degree of data structuring.The method of adding attributes to the bridge information model based on attribute interface files is characterized by standardization,efficiency,and scalability.
