Seismic and energy upgrading of existing buildings—full‐scale testing of retrofitted masonry‐infilled RC frames

Taking into consideration the seismic vulnerability and poor energy performance of European building stock, increasing socio-economic environmental need for integrating upgrading with efficiency improvement, an experimental study involving lateral load testing full-scale one-story one-bay masonry infilled RC frames load-bearing walls was carried out in framework SupERB research project aiming to investigate integrated systems. The approach is based on use textile reinforced mortar (TRM) overlays combined either traditional thermal insulation (extruded polystyrene, XPS) or thermally efficient incorporating phase change material (PCMs). proposed can be applied exterior face structure, so as facilitate its application real structures easiest possible way minimum disturbance inhabitants buildings. In this paper, only structural masonry-infilled retrofitted presented, while benefits will presented a separate paper. Thus, assessed through five that were different schemes TRM materials subjected in-plane displacement-controlled cyclic loading. following parameters investigated experimentally: number (one two layers insulation), PCM-enhanced layer contrast conventional XPS insulation, retrofitting configurations (placement sandwich form over and/or under novel insulation). From results obtained study, it concluded all systems examined have positive impact response system loading, ones having better compared one them than control specimen. cancels drawback frames, which at very small drifts they reach their maximum capacity after rapidly fall bare frame, providing capacities above 80% peak up 2%. tests whether included PCMs contributed distribution cracks infill delayed premature brittle failures. presence had also advantage remained intact throughout preventing debris plane both unretrofitted sides.
