The lack of experience in the early days causes problems today regarding a combination of corrosion and fatigue of the tendons. Wire breaks can lead to structural failure without warning. Acoustic emission analysis is the only reliable monitoring method to prevent catastrophic damage. Through an acoustic simulation of the structure and its fusion with measurement data, the research project "Digital Twin for the Simulation of Acoustic Emission Wave Propagation in Prestressed Concrete Elements" lays the foundation for optimizing the monitoring systems.
