Seismic Vulnerability of the Pisan Tower at the Norman Palace in Palermo

Abstract

This work presents the results obtained from the implementation of the "knowledge construction path" of a complex historic/monumental building such as the “Pisana” Tower, part of the “Palazzo dei Normanni” in Palermo, a preliminary and preparatory procedure, used in the italian construnction codes for the existing buildings, for structural modelling aimed at seismic safety of the building and the subsequent project of interventions. The work also presents the structural design for the temporary structural system placed in the North-East cantonal of the Tower, which involved the installation of a steel frame inserted inside the Piazzi library.
