During the first few months of the project, we reviewed the archives of the Chair of Bridges and identified the Slunjčica Bridge as a representative arch bridge (WP1) that will be the focus of our further research. Based on our previous studies, arch bridges are of particular interest regarding their seismic behaviour. Furthermore, the bridge location and the use of de-icing salts during winter months require investigation of potential bridge degradation due to corrosion.
Currently, we are collecting all available documentation on the bridge from the archives and preparing for the inspection of the Slunjčica Bridge to determine the structural condition and collect data relevant for engineering load analysis (WP2), bridge degradation assessment (WP3), and numerical modelling and simulations (WP4). We are analysing the bridge documentation and preparing the sequence and the scope of the visual inspection and non-destructive testing of the arch, piers, and the underside of the superstructure.
For non-destructive testing, we will use the following existing equipment:
- Ultrasonic pulse velocity testing device V-Meter Mark IV
https://www.croris.hr/oprema/oprema/5427 - Profometer 630 AI – device for reinforcement detection, determination of concrete cover, reinforcement diameter, and half-cell potential measurements
https://www.croris.hr/oprema/oprema/5428 - Schmidt rebound hammer (sclerometer)
https://www.croris.hr/oprema/oprema/5430 - Resipod – device for measuring the electrical resistivity of concrete
https://www.croris.hr/oprema/oprema/5429 - Crack width microscope

We have received permission from the road authority Hrvatske ceste d.o.o., responsible for the management, construction, and maintenance of state roads, to carry out the bridge inspection for research purposes. We would like to express our gratitude for their support and cooperation.
