Abstract of the dataset | Between May 5 and 7, 2025, extensive experiments were carried out on the openLAB research bridge. The test program was structured as follows: • Day 1: Static and dynamic measurements in the reference state • Day 2: Loading of the bridge using hydraulic jacks up to the ultimate limit state (yielding of prestressing steel) • Day 3: Local damage of prestressing tendons (cutting wires at several locations) The present dataset contains force and displacement measurements from the load test conducted on Day 2. The load was applied locally to precast element (PE) 2.1 (Field 2, PE axis 1) using two hydraulic jacks and increased up to 400 kN. Displacements were measured at five different positions along PE axis 1. Details on the measurement setup can be found in the attached file readme.txt.

(see attachment) Value of the data: • Validation and calibration of finite element models (FEM) • Comparison with geodetic measurement methods (e.g., total station, drone survey) • Basis for interpreting data from additional monitoring systems (e.g., distributed fiber optic sensing, acceleration measurements, acoustic emission monitoring, etc.) The provided Python script enables data import, post-processing, and visualization of the measurement data (see example figures). | |

Project abstract | The aim of the IDA-KI (Infrastructure Data Analysis with Artificial Intelligence) research project is to develop methods for the automated analysis and evaluation of monitoring data. The validation is carried out using real measurement data recorded on a 45 m long research bridge (openLAB). First, the reference condition of the bridge is measured with and without service loads over a period of one year. Subsequently, load tests are carried out in a targeted manner up to the severely damaged state and significant damage to the structure is actively induced. At the same time, redundant sensors will be damaged or manipulated so that a real database with specific signal characteristics for metrological and structural anomalies can be created. This will create an important basis for the development of evaluation methods (also based on machine learning) so that measurement errors in monitoring data can be corrected in the future and differentiated from structural damage. | |
