Abstract

Villa dei Misteri, one of the most famous domus in the ancient city of Pompeii, was protected by building reinforced concrete frames roofs; in recent years timber and steel struc- tures have been preferred. The evaluation of their health status requires a detailed study by means of a multidisciplinary approach, which should include geometrical surveys, damage assessment based on both in situ and laboratory diagnostic tests, UAV (Unmanned Aerial Ve- hicles) remote sensing to inspect area and coverings not easy to reach in safe, etc. In this pa- per the preliminary results of ambient vibration measurement, as basis for seismic safety assessment are presented. The evaluation of the structural capacity, to be compared to the seismic hazard at the site, is not easy due to the presence of quite different elements, such as the original masonry walls, the concrete frame roofs as well as wooden and steel structures. 15 seismometers connected to a recorder were used in two different layouts. The first one was used to analyse the dynamic characteristic of the soil with the underground structures and the effects of the trench, which surrounds the Villa at three sides In the second layout sensors were deployed on the structural elements of the coverings to analyse their behaviour and the interaction with the original masonry walls.
