BIM information-based bridge part classification coding method

Abstract

The invention discloses a BIM (Building Information Modeling) information-based bridge component classification coding method, which comprises the following steps of: obtaining geometric information and non-geometric information of all components in a bridge model according to BIM information of a bridge; adding category screening conditions according to the geometrical information and the non-geometrical information of the components, and screening out the components belonging to the same category from all the components; iFD codes are added to all the components, and the IFD codes of the components belonging to the same class are the same; in all the categories, EBS codes are added to all the sections of the components contained in part of the categories, EBS codes are added to all the components contained in the remaining categories, and the EBS codes are different from one another. According to the method, the same type of components are screened out according to the geometrical information and the non-geometrical information of the components, the same type of components are automatically subjected to EBS encoding in batches, the situation that errors occur due to the fact that long encoding parameters are manually input one by one is avoided, and the encoding efficiency and accuracy can be improved.

Description

technical field [0001] The invention relates to the application field of bridge construction BIM, in particular to a method for classifying and encoding bridge components based on BIM information. Background technique [0002] Building Information Modeling, or Building Information Modeling, or BIM for short, is a digital electronic model that contains all information about facilities, a virtual substitute for facilities, and a knowledge resource for facility information sharing, providing a reliable basis for decision-making. At present, BIM technology has become a popular research field in the civil engineering industry, but the imperfection of BIM technical standards in the field of bridge engineering limits the application of BIM in the field of bridge engineering. [0003] In recent years, the BIM-based project management platform has gradually developed into an important means to improve the management level of engineering projects, but how to quickly name and code the ...
