    Three Finite Element Models of the openLAB Research Bridge
    (Technische Universität Dresden, 2026-04-10) Eisermann, Cedric; Sprenger, Bjarne; Lila, Kleo; Schnellenbach-Held, Martina; Marx, Steffen
    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.
