DFOS Measurements at New Highway Bridge

Institute of Engineering Geodesy and Measurement Systems, Graz University of Technology, started together with the project partners AIT and ACI Monitoring the distributed fiber optic sensing (DFOS) measurements at the Aurachbruecke. The new Aurachbruecke is the tallest bridge at the Austrian Highway A1 operated by ASFINAG. The reinforced concrete bridge with 6 spans is going to replace the existing steel concrete composite bridge. Fiber sensing cables have been directly embedded into the concrete and measurements are made at different construction stages and at dedicated excitation experiments with shakers. Finally, the entire new bridge will be shifted from the preliminary pillars to the final pillars as shown.
