The aim of the present paper is to introduce ground penetrating radar (GPR) tests as a support of the structural identification for complex structures as the bell tower of the Cathedral of Trani (Bari, Italy); in particular, the structural identification has been performed by means of the Operational Modal Analysis (OMA) and subsequently the identified modal parameters have been utilized for the updating of a Finite Element model. Nevertheless, considering that the walls of the tower are composed by layers of different thickness and properties, the updating procedure has been implemented matching the results of the GPR tests. The possibility of using the GPR technology for foreseeing the internal composition of the building walls is here discussed and analysed together with the description of all the phases of dynamic identification and tower model updating.

Abstract
The aim of the present paper is to introduce ground penetrating radar (GPR) tests as a support of the structural identification for complex structures as the bell tower of the Cathedral of Trani (Bari, Italy); in particular, the structural identification has been performed by means of the Operational Modal Analysis (OMA) and subsequently the identified modal parameters have been utilized for the updating of a Finite Element model. Nevertheless, considering that the walls of the tower are composed by layers of different thickness and properties, the updating procedure has been implemented matching the results of the GPR tests. The possibility of using the GPR technology for foreseeing the internal composition of the building walls is here discussed and analysed together with the description of all the phases of dynamic identification and tower model updating.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
