    Distributed fiber optic sensor data of the openLAB loading tests from 2025-05-05 to 2025-05-07
    (Technische Universität Dresden, 2025-12-11) Richter, Bertram; Ulbrich, Lisa; Collin, Fabian; Kielreiter, Anett; Kirchner, Andreas; Ganß, Martin; Wittmann, Stefan; Nöther, Nils
    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.

    Experimental procedure for the tests on the openLAB from 2025-05-05 to 2025-05-07
    (Technische Universität Dresden, 2025-12-19) Richter, Bertram; Ulbrich, Lisa; Kielreiter, Anett; Jansen, Andreas; Röder, Robert; Walker, Maria; Jesse, Frank
    This dataset presents the experimental campaign and monitoring data from the openLAB research bridge, a large-scale laboratory structure located in Bautzen, Germany. The experimental campaign with damaging loading tests was carried out between 2025-05-05 and 2025-05-07 (inclusive). The dataset includes the protocol of the measurement campaign, monitoring data for air temperature and structural temperature, humidity, solar radiation as well as tilt measurements. Data are sourced from an electrical Gantner Instruments measurement system (Q.station 101T, with various Q.bloxx modules) and several testo 176 T4 data loggers. Datasheets for all sensors and data loggers are provided. The repository provides the data in Comma Separated Values (CSV) and Tab Separated Values (TSV) format. Each file includes a header specifying the names of the data columns. Additional details, such as units and sampling frequency, are provided in this README file. Each CSV file contains a Timestamp column that records the time of each sample as a datetime string in ISO 8601 format, without time zone information. All timestamps are in Coordinated Universal Time (UTC). Sensor data is represented as decimal numbers.
