Dry "mortar-free" infill panels for sustainable architecture in high seismicity areas

Recent earthquakes have shown how infill panels and partitions, widely used as non-structural elements in reinforced concrete frames, are significantly vulnerable for both in-plane and out-of- plane actions. Moreover, their damage strongly influences repair costs for typical multi-storey buildings. The innovative technology for infill panels is extended here for internal partition too, taking into account both their seismic and energy efficiency and acoustic performances, including a comparison with respect to conventional infill typologies, highlighting critical aspects and strong points of each of them.
