The phenomenon of bradisism and seismic risk
The bradyseisma typical phenomenon of the Flegrei fields, manifests itself through Continuous lifting cycles and soil lowering due to variations in the pressure of underground fluids and volcanic processes. Although related earthquakes generally present magnitude contained, their superficiality makes them particularly perceptibleaccentuating the structural critical issues and highlighting the Risk for the safety of the population.
Criticality of the building heritage
Most of the buildings in the area – especially in Pozzuoli, where about 90% of the buildings dating back before 2000 – it was not made following the most recent anti -seismic regulations.
The studies of Iervolino et al. highlight how, in reinforced concrete buildings, Retrofit interventions can reduce the risk of fatality of over 70%. These data indicate that, in the presence of repeated shocks, even moderate intensity events can cause significant damage, making it urgent the adoption of innovative solutions for safety.
Advanced technologies for the protection of buildings
There repetitiveness of seismic events requires interventions that go beyond traditional passive systems.
Systems Active Mass Damper (AMD) of anti -seismic Isaac They represent a revolutionary solution: these devices do not absorb the energy of the earthquake by degrading themselves, but work as active machines that react in real time to the oscillations. Thanks to an intelligent mechanism based on electronically controlled counterweights, AMDs operate continuously for millions of cycles, ensuring constant protection without damaging themselves. This non -invasive technology, in fact, can be installed on existing buildings Without altering its functionality, avoiding the typical interruptions of other passive systems that require replacement after each seismic event or the evacuation of the building.
Investing in Active Mass Damper systems seems to be the more promising strategy to mitigate the seismic risk in the Flegrei fields. These devices, operating continuously without suffering damage, exceed the limits of traditional passive systems, guaranteeing constant protection of buildings and increasing the comfort of the occupants. With a non -invasive approach, AMDs present themselves as an ideal solution for the retrofit of the existing building heritage, offering a concrete way to protect the population in an area characterized by frequent shocks.
Comment Alberto BussiniCEO of Anti -seismic Isaac: “Active Mass Dampers represent a revolutionary technology because, unlike the traditional systems that degrade by absorbing energy, our devices operate continuously for millions of cycles. It is thanks to these characteristics, for example, that ISAAC technology has recently been installed on the new Piloti Tower of Genoa, designed by Renzo Piano, to counter the stresses caused by the different climatic conditions. The same applies to the adoption of our systems in the context of the seismic improvement project of the F. Middle School of Bartolo, on the initiative of the municipal administration of Buti in Tuscany “. Bussini concludes: “It is essential that technologies such as ours are increasingly accessible. For our part, in order to extend it to a large number of buildings and support the public administration in the difficult task of making our cities increasingly safe, we are also working to develop leasing models with strategic partners that accelerate and facilitate adoption ” .
Anti -seismic Isaac: who it is and what does it do
Anti -seismic Isaac Founded in 2018 by the homonymous research project of the Polytechnic of Milan, Isaac develops Intelligent solutions for seismic protection And it is the first in Europe to have patented an active technology dedicated to existing buildings, without the need for structural or invasive interventions.
Isaac’s advanced solution is applicable to any type of construction, from homes to condominiums, offices, churches, bell towers, towers for telecommunications, schools and hospitals.
The ISAAC system uses a combination of machines installed on the cover of the building e sensors positioned in strategic points, allowing the installation from the outside without having to clear the property. Classified according to the ISO3010: 2017 standard as Active Mass Damper (AMD), the technology patented by Isaac represents a turning point in the sector thanks to its ability to improve the structural behavior of buildings during earthquakes, reducing oscillations and efforts on the structures. This is possible thanks to forces generated in real time by control algorithms based on the accelerometric measurements detected by the sensors installed.
Isaac’s Active Mass Dampers, located on the roof of buildings, work as Controlled counterweights electronicallydamaging the fluctuations caused by seismic events, vibrations or wind, without altering the architecture of buildings. This innovation has already led to the installation of over 150 Isaac machinery in Italy in three years. Among the most recent Isaac systems stand out those on the new Pilot Torre di Genova, on the middle school of the Municipality of Buti in Tuscany and on hotels of prestigious chains, as well as important hospitals in which the works are underway.
