Dr. Eftychia Apostolidi,
Junior Research Group Leader Structural Mechanics
Bridges are so formative that their construction has become a figure of speech for overcoming obstacles. Since ancient times, they have connected shores, people and cultures. Changing loads on these structures require ever new analysis methods and calculation models.


To date, data from monitoring systems on structures (primarily bridges) has been used for the structural assessment and maintenance measures of such structures. In a similar way, sensor systems installed on vehicles are used to monitor vehicle components and the track system. Inherently, however, the respective sensor systems collect data that contain further information: An instrumented train passes over a large number of bridges on its journey and a large number of trains pass over an instrumented bridge.
Project objective
The objective of the project is to develop, implement and validate a digital tool for the in-situ monitoring of railroad bridge structures in the context of a sensor data-based predictive maintenance concept using a BIM-integrated Digital Twin (Digital Twin), based on Artificial Intelligence. The core objective is to develop a template for a highly automated and improved assessment (resonance hazard, structural safety, remaining service life) of existing railroad bridges.
Implementation
The status data obtained by dynamic monitoring is taken into account via an automated and continuous update of the actual status of the digital twin. Based on the condition data, an artificial intelligence decides on any necessary adaptation of the structural models (bridge and vehicle) to the existing condition (structure identification, system calibration) by considering the mechanical correlations of the structure
