“…This method has been used for the dynamic identification of monuments like the research on the seismic response of a prestigious masonry palace and the exhibited damage pattern which retrofitted after the 2009 earthquake in L'Aquila [14]. Also the resolution of the identified modal parameters in relation to the instrumentation strategy (dense or not dense sensor distribution) and the building's history is discussed to another research on the medieval church of Sant'Agata del Mugello, a Cultural Heritage building with a rich and complex constructive history and many repair operations [15].…”

Evaluation of structural behaviour of a masonry Venetian Church with pointed vault, is presented in this paper through an analysis following the neccessary steps of a monument study. Having a detailed geometric model and the material estimation, the finite element method was used in order the influence of specific structural parts of the structure like masonry butresses and walls connections to the structural behaviour are examined. The comparison of the eigenfrequencies which are estimated by in situ measurements and finite element modal analysis is used to model identification. The response spectrum analysis, the static analysis for subsidence of some parts and the transient analysis of a specific seismic excitation are used to evaluation of the church strength. Comparison of modal analysis results with the structural pathology is helpful to this research about the structural behaviour of the church.

“…The modal anomalies, captured during two experimental campaigns using Enhanced Frequency Domain Decomposition (EFDD) [2], were applied to establish a relation between the dynamic response and the history of restorations. The study disclosed the effect of sensor placement on the extracted modal properties [3].…”

Monumental structures and archeological sites are often exposed to intense ambient and anthropic vibrations which might compromise their structural integrity. Monitoring these precious assets allows to assess their overall conditions and highlight possible changes in the behavior of the structure. In this paper, the effects of vibrations on the Circus Maximus archeological area are investigated. A wireless structural health monitoring system was used to record accelerations from July 2022 to January 2023. During this period, several concerts and events were held in the area. The acceleration records were used to perform dynamic characterizations of the site. Different numbers of sensors and configurations were used to assess the influence of spatial resolution. The modal properties were obtained through the frequency domain decomposition technique and compared to those from previous studies. Overall, a reduction of the modal frequencies has been observed which requires further investigations. 4030COMPDYN 2023 9 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.
