The most dominant type of damage in the February 2023 Kahramanmaras earthquakes was the failure of infills walls. This paper shows just part of the effects of these earthquakes on the infills and concequences on the building inventory and people. The data was collected during the reconaissance field mission one month after the earthquake. In all cities visited damage of the infilled RC frame structures was devastating. Poor behaviour and heavy damage due to the interaction of flexible frames with the stiff infill walls showed that traditional infills (mortar connection between frame and infill) are conceptually wrong system for the buildings in earthquake active areas. Beside heavy in-plane damage, inadequate connection between frames and infills led to the widespread out-of-plane collapse of infill walls. This has jeopardized people and escape routes during the earthquakes as well it produced significant economic loss. Many other earthqukes before showed that this is not acceptable anymore, but this one confirmed it. Therefore, this paper also proposes isolation of infill walls as a solution that can prevent such a devastating effects in future earthqaukes. Although isolation of infills is presribed in the codes it is not in use due to the fact that there are no simple and easy applicable solutions on the market. With the aim to fill this gap, a system presented here is developed. Its goal is to provide functional and easy applicable solution to the designers and construction companies and workers. Experimental tests on the full scale specimens of isolated infilled RC frames are shown, confirming the effectiveness of the isolation system. Infill walls with windows, doors and full walls are tested under various earthquake loading conditions. Furthermore, comparison with the traditional system was done, showing benefits and improvements brought by this system.
