Abstract
Buildings built in Italy after the 1950s represent about 50% of the existing building stock. Currently they have structural and energy deficiencies, compared to news standards, and their maintenance is considered, in many cases, unsustainable.
In recent years, several studies of these buildings have been carried out, but many of this have addressed individual problems relating to structural, energy and architectural deficiencies, without a real interdisciplinary coordination. For this reason, a study has been undertaken which aims to address these issues in an integrated way through a multidisciplinary approach in the retrofit of existing reinforced concrete buildings that deals with the aspects relating to structural strengthening, energy requalification and architectural renovation. In this paper only the first step of this study is presented related the structural aspects; in detail, a pushover analysis was carried out in order to define the performance point of the combined system (concrete reinforced building and steel exoskeleton) and the results of the analysis are presented and discussed.
