Abstract

In this paper dynamic identification techniques for a non-destructive evaluation of the dynamical characteristics of cultural value buildings are applied to the medieval Normand tower of Craco (Matera, Italy) that is built next to a landslide area. As a consequence the little medieval town was abandoned starting from 1968 when the effects of the landslide on the buildings were more pronounced. The tower is one of the few building still standing as it is built on a fixed stiff ground. More in detail, the paper presents the in-situ tests results and the preliminary finite element model of the tower. The tower was built in the XI century for defense against enemy attacks. It has a symmetric square plan, with dimensions 11 m x 11 m, and it is 20 m tall. Inside a cistern in reinforced concrete was placed in 1949. It has no interaction with the structure of the tower; nevertheless it makes more difficult to install the sensors of the testing set-up. The results of the experimental tests have been analyzed to estimate the modal parameters through Operational Modal Analysis. The results will give indications about the health status of the tower in order to assess its effective risk of collapse and prevent the structure from the damage due to dynamic forces and the close landslide movements.
