Simulated natural frequency time series for SHM testing and validation

The dataset holds two numerically generated time series of natural frequencies obtained from the digital twin of a reinforced concrete arch bridge calibrated with respect to the results of an Operational Modal Analysis (OMA) test. The natural frequency time series refer to the first six modes of the bridge. The first time series takes into account the concurrent influence of temperature and noise. The second time series accounts for the concurrent influence of simulated damage, temperature and noise. Realistic time serie have been obtained. They can be used either to test data-driven or model-based approaches. The time series of temperature is also provided, as measured by a local meteorological station.
