Structural Vibration Solutions, in collaboration with Dewesoft, has been granted permission to conduct measurements on the Tomacevo Bridge as part of an innovative project led by the Slovenian company CESTEL. The project is part of the overall international BIM4CE project, which involves nine EU member countries conducting bridge monitoring across Central Europe using real-time data and digital twin technology.

The motivation for such a project is significant, as many concrete bridges worldwide are aging, raising concerns about their durability and safety. It is well-known that environmental factors such as wind and weather deteriorate concrete structures, and there have been instances where standard maintenance procedures failed to detect damage, leading to severe consequences, including collapses.

We are excited to share that ARTeMIS-SHM software is being utilized in this project. ARTeMIS-SHM operates by continuously analyzing the data sent directly via FTP from Dewesoft IOLITEi 3xMEMS sensors installed on the Tomacevo Bridge.

Our software stands out from other structural health monitoring (SHM) methods as it can determine mode shapes, natural frequencies, and damping ratios solely from output response data. This capability allows the software to analyze measurements directly from the operating structure, providing a more accurate representation of actual load effects and enabling timely responses to changes, ensuring necessary maintenance can be performed before damage becomes critical.

For nearly a year now, ARTeMIS-SHM has been continuously analyzing and reporting the condition of the Tomacevo Bridge in Slovenia.

The analysis is conducted automatically using ARTeMIS Modal Pro, including a list of SHM plugins. It is running as a Windows service using the SHM Automation Service plugin on a Windows server in Denmark. Data is received from the bridge every 10 minutes, and the Automatic File Upload plugin merges the 10-minute files into two 10-hour files per day. These merged files are automatically pushed to the ARTeMIS Modal Pro analysis engine, where modal analysis and mode tracking are performed. The service can be stopped at any time to allow the ARTeMIS Modal project to be viewed in the desktop version.

We will incorporate damage detection into the analysis once we have collected data for approximately one year. Having a full year of data will allow the damage detection setup to account for natural seasonal changes.
