Interactions between Seismic Safety and Energy Efficiency for Masonry Infill Walls: A Shift of the Paradigm

Currently, the upgrade of existing reinforced concrete (RC) buildings focuses only on energy retrofitting measures due to current policies promoted in scope European Green Deal. However, structural deficiencies are not eliminated, leaving building seriously unsafe despite investment, particularly seismic-prone regions. Moreover, envelopes RC responsible for their efficiency and seismic performance, but these two performance indicators usually correlated. They frequently analyzed independently from each other. Based this motivation, research aimed perform a holistic assessment five different types masonry infill walls (i.e., non-strengthened walls, with strengthening, one wall strengthening). This was performed three-step procedure: (i) by analyzing heat transfer coefficient type; (ii) out-of-plane vulnerability; (iii) cost–benefit assessment. Therefore, global analysis performed, which (structural energy) were evaluated. In addition, state-of-the-art review regarding strengthening techniques (independent independent combined plus strengthening) is provided. From study, it observed that use external thermal insulation composite system reduced about 77%. strength capacity 9%. On other hand, textile-reinforced mortar improved deformation 50% 236%, did sufficiently reduce coefficient. There need combine both simultaneously improve parameters.
