IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishComparisons are made between the well-known non destructive technique of flat-jack used in masonry and the recently introduced PNT_G penetrometer, best suited to in situ measurements of mortar strength. A method is proposed for determining the stress-strain response law of masonry walls subjected to vertical loads by means of PNT-G on mortar joints and axial tests on the blocks. The technique gives the best results in case of weak mortar respect to blocks
