An analysis on technological plant retrofitting on the masonry behaviour structures of 19th century Traditional Historical Buildings (THB) in Rome

The aim of this paper is to investigate the actual conditions of masonry load-bearing structures of historical and traditional buildings as a result of interventions on building plant installations that have occurred over the years. The reference building stock is between 1880 and 1942 during one of the most important urban developments in Rome. In recent years, however, there has been insufficient interdisciplinary communication between stakeholders in the fields of cultural heritage preservation and energy efficiency. In particular, in reference to the widespread demands for plant improvement of historical buildings from the late nineteenth century which are often subject to interventions of functional and technological upgrading with a devastating impact on the nature of the original constructive elements. A preliminary analysis was conducted with FEM to evaluate the state of conservation resulting from invasive interventions on the load-bearing masonry structures
