Abstract
Vibration-based Structural Health Monitoring is an ongoing field of research in many engineering disciplines. As for civil engineering, plenty of experimental structures have been erected in the past decades, both under laboratory and real-life conditions. Some of these facilities became a benchmark for different kinds of methods associated with Structural Health Monitoring such as damage analysis and Operational Modal Analysis, which led to fruitful developments in the global research community. When it comes to the continuous monitoring and assessment of the structural integrity of mechanical systems exposed to environmental and operational variability, the robustness and adaptability of the applied methods is of utmost importance. Such properties cannot be fully evaluated under laboratory conditions, which highlights the necessity of outdoor measurement campaigns. To this end, we introduce a test facility for Structural Health Monitoring comprising a lattice tower exposed to realistic conditions and featuring multiple reversible damage mechanisms. The structure located near Hanover in Northern Germany is densely equipped with sensors to capture the structural dynamics. The environmental conditions are monitored in parallel. The obtained continuous measurement data can be accessed online in an open repository. That is the foundation for benchmarks, consisting of a growing data set that enables the development, evaluation, and comparison of Structural Health Monitoring strategies and methods. In this article, we offer a documentation of the test facility and the data acquisition system. Lastly, we characterize the structural dynamics with the help of a finite element model and by analyzing several month of data.

N1 - Funding Information: If it had not been for the Institute of Meteorology and Climatology of Leibniz University Hannover, the planning, installation, and maintenance of the test structure would not have been possible. Much credit goes to Ulrich Meyer, Prof. Groß, Prof. Seckmeyer, Prof. Raasch, and Dipl.-Geophys. Holger Schilke. We humbly appreciate their support and dedication. The authors would further like to thank the Leibniz University IT Services (LUIS) for facilitating the upload of the large amount of data associated with LUMO. This research has been financed by the Federal Ministry of Economic Affairs and Energy of the Federal Republic of Germany (project: German Research Facility for Wind Energy–Phase 2, FKZ 0325936I) and Deutsche Forschungsgemeinschaft (project: SFB 1463–Integrated Design and Operation Methodology for Offshore Megastructures). We would like to gratefully acknowledge their support. Open Access funding enabled and organized by Projekt DEAL.
