Learning Professional Ways of Beingnt vibration tests were performed on the footbridge to extract the modal parameters of the structure such as natural frequencies, damping ratios, and mode shapes. The modal properties were identified from ambient vibration tests adopting the Stochastic Subspace Identification (SSI) technique. The av

Learning with Damaged Colonial Places civil structures, such as thermal and nuclear power plants. Acoustic emission (AE) detection can be potentially used to establish the real-time passive SHM method. Conventional AE sensors are made from piezoelectric materials, whose operational temperature is limited up to 200 °C. Hence, it is diff

Through the adoption of an operation modal analysis (OMA) technique, it was then possible to construct a large database of the dynamic features concerning the studied viaducts. This database may be ex

In this study, amplitude dependence of damping ratio was also investigated, since a change in the modal damping ratio can be used for damage identification but its dependence on amplitude rem
