Sistemi costruttivi innovativi per tamponature in laterizio basati sull’utilizzo di giunti deformabili

Within the INSYSME Project, funded under the 7th Framework Program by the Commission of the European Communities and aimed at developing innovative systems for clay masonry enclosure walls, the University of Padova and ANDIL proposed a construction system named DRES (Damage Reduction Enclosure System). The system is made of a single-leaf clay masonry wall, with three horizontal deformable joints within the clay unit rows, to be employed in RC frame buildings in regions prone to medium/high intensity earthquakes. To understand the behaviour of this system, an experimental campaign on real-scale, one-bay, one-storey height RC frames, infilled with the new masonry system, was performed. The tests combine cyclic in-plane and monotonic out-of-plane loading of the specimen. This paper presents the results obtained on several variants of the DRES system, and a reference plain masonry enclosure wall.
