Greater resistance to earthquakes with a new plaster developed by ENEA

Greater resistance to earthquakes with a new plaster developed by ENEA

A non-invasive technique to reinforce the houses hit and damaged by earthquakes has been recently developed by the ENEA Research Centre in Casaccia in collaboration with Roma Tre University and support by Fibre Net within the COBRA1 project funded by Regione Lazio.

The structure, reinforced with innovative, low-cost and easy-to-apply Made-in-Italy solutions, has successfully resisted to the tests thanks to the coating of plaster reinforced with glass fibre; this structural system involved two out of three walls, is little invasive and low-cost, and can be implemented without home evacuation.

“The walls strenghtened with fiber glass meshes withstood earthquakes amplifying the level of intensity of ground motions up to 220%, double the most violent earthhquakes of 2016, while the unreinforced wall was badly damaged already at a 120% intensity level, that of the ground motions of the earthquake occurred two years ago”, pointed out Gerardo De Canio, Head of the ENEA Laboratory of Technologies for Sustainable Innovation.

“The innovation, entirely developed in Italy, consists in a composite material applicable,  together with the traditional refurbishment of buildings, on the external walls”, said Gianmarco De Felice, of the Roma Tre University of Rome and coordinator of the project. “Composite materials are already in use in the aviation and automobile sectors, but not in the building sector. That's why we hope that the outcomes will pioneer innovation also in this important field.

Experimental data have been acquired in 3D and shared on the DySCo virtual platform developed by ENEA, so that experts from all over the world can actively take part in the tests.
