Abstract of the dataset | From May 5 to May 7, 2025, extensive experiments were conducted 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 using hydraulic jacks up to the ultimate limit state - Day 3 (2025-05-07): Localized damage to the prestressing tendons (cutting wires at multiple locations) This dataset includes three finite element (FE) models of the openLAB research bridge which were used to simulate the load tests conducted on Day 2. The load was applied locally to the prestressed element (PE) 2.1 (span 2, PE axis 1) using two hydraulic jacks, incrementally increasing the load up to a total of 400 kN. The three FE models were independently developed using different FE software solutions and feature different element types: - FE model 1: ATENA, volume element model - FE model 2: DIANA FEA, volume element model - FE model 3: SOFiSTiK, combined beam-shell element model The dataset includes all necessary input files to recreate the FE models in their respective software environments and reproduce the simulation results of the load tests. | |

Project abstract | The Priority Programme 2388 “Hundred Plus” aims to significantly extend the service life of infrastructure through cutting-edge maintenance strategies and advanced digital technologies. During Phase 1, the focus was on automating the collection of structural data, creating highly accurate 3D models, and integrating real-time monitoring data into digital twins to enable continuous structural assessment. These advancements facilitate early damage detection and the development of proactive maintenance measures. Building on these achievements, Phase 2 will concentrate on refining condition indicators and predictive models to provide more precise and comprehensive assessments of structural health and to forecast the remaining service life of infrastructure. Additionally, methods for deriving actionable recommendations will be developed to support predictive and prescriptive maintenance strategies. These approaches will be validated on real-world structures, including the Nibelungen Bridge in Worms and the “openLab” research bridge in Bautzen. | |
