Cultural Heritage Recovery Interventions Through Steel Endoskeletons: A Case Study

The existing buildings in Italy represent most of the building heritage, with significantly different characteristics in relation to the type and structural scheme used, the activities that take place in them, the materials used and the current state of conservation. Recent and past seismic events have highlighted the high vulnerability of the existing building heritage, as well as the need to identify intervention strategies for the adaptation, improvement, or seismic strengthening of these buildings (or portions of them) characterized by high versatility, ease of application, reversibility and, where possible, economy. In this context, the application of structural strengthening/consolidation systems in steel is presented as an optimized and performing solution able to merge the excellent mechanical performance of the material, in strength and ductility, with the ability to meet the current regulatory requirements for buildings in seismic areas through simple and easily applicable and installable systems. The article in question studies an intervention of improvement and reorganization of a masonry building or historian, a Saracen tower in Cardeto (RC, Southern Italy), in order to expose a methodology of analysis and intervention aimed at improving and consolidating it.
