AIT's structural dynamics team recently successfully completed a pioneering research project on monitoring a highway bridge using distributed fiber optic measurement technology. On behalf of ASFiNAG and in collaboration with partners IGMS of Graz University of Technology and ACI Monitoring, a 66-metre-long measuring field on the newly constructed Aurach Bridge on the A1 Westautobahn near the Regau junction was equipped with fiber optic sensor cables. The measurements extended over several phases and were carried out under dynamic excitation and real traffic conditions.
Fiber optic measurement systems from LUNA, fibrisTerre and Febus Optics as well as ESR strain gauges from Heidenhain and Motion Amplification® cameras with associated software were used. These advanced technologies enabled precise and diverse data analysis that provided valuable insights into the bridge's behavior.
In the following video, AIT expert Vazul Boros explains the basics and benefits of this innovative technology and provides a comprehensive overview of the exciting research project (in German):
