    OpenBridgeLAB Output-Only Acceleration Data - Reference State, Damage State 1, and Damage State 2
    (Technische Universität Dresden, 2026-08-28) Moeller, Max; Juler, Tobias; Patzelt, Adrian; Lenzen, Armin
    The OpenBridgeLAB, a testing bridge erected to investigate structural health monitoring methods, was equipped with 32 uniaxial piezoelectric acceleration sensors to measure the structural response under ambient excitation. The bridge is a prestressed concrete bridge consisting of three spans, each with a length of 15 m. The bridge deck comprises three prefabricated T-beam elements. For the investigations, only Spans 1 and 2 were equipped with accelerometers, as Span 3 is structurally decoupled. The dataset consists of three different ensembles: the Reference State (RS), in which the bridge is in an undamaged condition, Damage State 1 (DS1), and Damage State 2 (DS2). Following the acquisition of the RS measurements, damage was introduced in Span 2 of the OpenBridgeLAB. A second damage was subsequently introduced in Span 1 after the measurements for DS1 had been captured. A detailed description of the damage scenarios and their locations is provided in the companion paper. In addition to the dataset, a datasheet is provided. The datasheet contains a detailed description of the measurements, including the sensor positions, sampling rate, number of measurements, and data structure. This research is part of the SPP100+ Priority Programme funded by the German Research Foundation.
