Abstract:: In view of the problem of information management in bridge loading test and bearing capacity evaluation, a bridge carrying capacity evaluation system was developed through designing the system framework and establishing the application modules based on BIM modeling software Revit and SQL Server database. Finally, the system was applied to a prestressed concrete Ttype rigid frame bridge in the case study of real bridge, and to some extent its feasibility and effectiveness of the practical application was proved. The results show that loading tests simulated by threedimensional visualization technology, and all of testing related spatial information and data information are integrated and managed by BIM model. The management of information database makes data input, storage, query and modify more convenient and efficient. BIM model can be directly converted into finite element model, and the structure analysis function is extended to make the bridge carrying capacity evaluation more automatic. It can be convenient to compare the historical data of the bridge testing, take a look at the change of the index of different detection time, master the current situation and the trend of the bridge.
