The debate on interventions in the monumental buildings is more relevant than ever and enriches itself due to collapses caused by natural disasters, often preventing quick and effective repair intervention.

Abstract

The debate on interventions in the monumental buildings is more relevant than ever and enriches itself due to collapses caused by natural disasters, often preventing quick and effective repair intervention. This is the case of the Cathedral in Piazza Armerina, that even two years after the collapse of the vault, has not yet restored. The paper analyzes the various operational stages ranging from initial monitoring to the identification of the causes of the collapse mechanism, finally to the reconstruction project. The project takes into account the cul-tural values of the building and the improvement of its structural safety. The collapsed parts have to be reconstructed by means of stone materials with similar characteristics to the original ones. In addition, the rebuilt portion of the vault will be consolidated and connected to the not collapsed part with the application of FRP net and special restoration mortar. Static checks, by means of both traditional methods and finite element analysis systems, gave similar results, in conformity with Italian technical regulations.
