Residential buildings account for approximately 43% of total energy consumption, and therefore, it will be crucial to improve their efficiency to achieve climate neutrality by 2050. In Europe, approximately 60% of residential buildings date back to the 1980s, with 9% dating back to before 1919. With reference to Italy, approximately 25% have never undergone renovation work. In addition, these old buildings are characterized by low seismic capacity, having been built according to technical codes that lacked or had few prescriptions against seismic loads. This vulnerability was evidenced in many past earthquakes. The improvement of energy efficiency of buildings was often performed without any structural retrofits and without evaluating the susceptibility to seismic damage of the added systems. In this way, the latter seismic events have shown a large extent of damage in added coatings, resulting in substantial economic loss. This highlighted the need for integrated approaches, facing both seismic/energy issues to propose sustainable interventions. In this work, some experimental results from a two-story concrete frame structure with double-leaf infills, tested on a shaking table before and after integrated retrofit aimed at an overall energy-structural rehabilitation, are shown. A Glass Fiber Reinforced Polymer (GFRP) net is used to enhance structural performance, while a polyurethane foam covering both structural and non-structural parts increases thermal efficiency. The work highlights the Out-of-Plane (OoP) failure of infills under different boundary restraints and aims to demonstrate the effectiveness of the GRFP net in resisting overturning. As the interpretation of the collected data is still in progress, in this paper, the experimental results of the pre-intervention phase are presented and used to develop a Finite Element (FE) model for the assessment of the retrofit intervention on the infills. Nonlinearities would be added to the model to achieve a complete match with the experimental data. © Fédération Internationale du Béton (fib) – International Federation for Structural Concrete.
