Cultural heritage, from ENEA a technology for seismic prevention
It is now possible to protect fragile monuments or frescoes that are likely to collapse in an earthquake thanks to ‘motion magnification’, an innovative technology applied for the first time by ENEA to the field of cultural heritage.
The technology can predict the behaviour of buildings or structures in the event of an earthquake, amplifying small motions caused by natural microtremors, making visible the motions of the analysed object, with a detail of a few thousandths of a millimetre.
ENEA will use this technology, developed by MIT and designed for medical and security applications, for the monitoring and seismic protection of cultural heritage, in combination with the shaking tables of the Casaccia Centre and the 3DVision system, with both field and laboratory tests.
“At ENEA we are able to combine this technology with the quantitative analysis of frequency values, obtaining a structural diagnosis of the element analysed. In practice, the analysis of magnified motion videos suggests in which parts of a building the motions caused by weak vibrations generated by the traffic, the wind, trains, etc., are more evident”, explained Vincenzo Fioriti from ENEA’s Sustainable Innovation Technologies Laboratory - LTIS.
“Thanks to this innovative technology, ENEA is able to plan preventive actions on the most damaged portions of masonry before a seismic event occurs and propose a technological and diagnostic offer unique in the world in the NOP and Horizon 2020 projects, in the fields of seismic prevention and safety”, underlined Gerardo De Canio, head of LTIS at ENEA.
