BIM-FEM-based bridge health assessment system and health assessment method

Abstract

The invention discloses a BIM-FEM-based bridge health assessment system and health assessment method, and the system comprises: a BIM bridge operation and maintenance management module which is used for classifying and storing related information generated in a bridge operation and maintenance process; an ANSYS bridge finite element safety calculation module which is used for calculating the stress state of the bridge; an information transfer module which is used for realizing information mutual feedback between the BIM bridge operation and maintenance management module and the bridge finite element safety calculation module; an information viewing module which is used for viewing the operation and maintenance management information and the structural stress deformation state of the bridge; and an information input module which is used for inputting basic engineering data and operation and maintenance management information of the bridge. According to the method, the problem that the BIM information model lacks effective structure safety analysis in the bridge operation and maintenance process can be solved, the advantages of visualization, coordination and simulation of the BIM technology are combined with the calculation advantages of finite element analysis software, and a reliable bridge safety evaluation function and convenient visual experience are provided for bridge operation and maintenance.

Description

technical field [0001] The patent of the invention is mainly used in the technical field of bridge health monitoring, and relates to rapid structural safety assessment of bridges during operation and maintenance, especially a BIM-FEM-based bridge health assessment system and health assessment method. Background technique [0002] BIM (Building Informatica Modeling) building information model, this technology is based on computer technology, combined with various project information of the entire construction project, constructs a three-dimensional visual building information model, and plays its corresponding role in the entire life cycle of the project. Compared with planning, design and construction, bridge operation and maintenance takes the longest time in the entire bridge life cycle, and BIM can play a better role in the operation and maintenance stage. The BIM-based bridge management system can effectively manage the inspection and evaluation information in the operat...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bridge health assessment system and health assessment method based on BIM-FEM. The problem to be solved by the present invention is: the current mainstream bridge BIM management system cannot effectively use the Bridge BIM model data and operation and maintenance information carry out finite element analysis work to further understand the stress and deformation state inside the bridge and predict the development trend. It is necessary to provide a combination of BIM and finite element analysis to meet the bridge health assessment and prediction needs
