Development of BIM-Based Digital Twin Model for Fatigue Assessment in Metallic Railway Bridges

The emerging Digital Twins have brought great revolution in the processes of monitoring and managing assets such as bridges. This work, which is part of a pilot project, aims to evaluate and simulate the fatigue behavior in metallic railway bridges (MRB) supported by a Digital Twin, which in turn is based on Building Information Modeling (BIM) capabilities. An integrated system based on appropriate software and consisting of three main modules (Input Module; Calculation Module; Output Module) is assembled. The current stage is promising, being possible not only to estimate the fatigue damage for different scenarios but also to visualize it and access other damage-related information.
