Abstract
Between 2025-05-05 and 2025-05-07, extensive experiments were carried out on the openLAB research bridge. The test program was structured as follows:
- Day 1 (2025-05-05): Static and dynamic measurements in the reference state
- Day 2 (2025-05-06): Loading of the bridge with hydraulic jacks up to the ultimate limit state
- Day 3 (2025-05-07): Local damage to the prestressing tendons (cutting wires at several locations)
This dataset contains distributed fiber optic strain sensing (DFOSS) data measured during the load test conducted on day 2. The load was applied locally to PE 2.1 (span 2, PE axis 1) using two hydraulic jacks and increased in steps up to a total of 400 kN.
