Abstract:With the proposal of a series of policies such as the digital transportation power, BIM technology has been an important starting point for the information technology. By analyzing the relationship between BIM and mechanical analysis data, the mechanical basic information based on BIM component concept is classified. At the same time, the dynamic visual analysis of mechanical data is realized through the rapid analysis method of bridge mechanical response based on BIM. Through this system, the dynamic comparison of monitoring results can be greatly perfected, the designers can be assisted to make the rapid decisions, and a certain theoretical basis is provided for the determination of construction schemes.
