Abstract: This paper describes a pilot project for the seismic monitoring of public buildings proposed by the Functional Centre of the Security Integrated Policies and Civil Protection Department - Marche Region (DPISPC) and the Ancona branch of National Institute of Geophysics and Volcanology (INGV). The aim of the pilot project is to associate to vulnerability profile more information about vibrational characteristics of the building and subsoil, in addition to the seismic instrumental history that describe the seismic shaking at the base of the structure. To start the pilot project with the available resources, 11 sites in the Regione Marche were identified where there are already permanent accelerometers at the base of public buildings and temporary measurements of ambient seismic noise were carried out, both inside and outside the structures. Frequencies and directions of the main spectral peaks of vibration of buildings were estimated, using spectral analysis techniques. The directional analysis was useful for interpreting the irregular morphology of some spectral peaks resulting from the standard analysis obtained with the composition of the horizontal components of motion. The collected information, combined with the geological and morphological classification of the sites, provide knowledge about seismic response of structures. Moreover, this approach will be compared to other case studies in which the seismic monitoring of individual structures is carried out with large instrumental and computational resources that allow precise and detailed results but difficult to largely apply on the territory.
