Seismic isolators and active heat sinks: what are they and what is the difference?
Install. Protect. Monitor.
Let's now see the difference between the seismic isolators and active heatsinks, as I-Pro 1.
The main differences between an isolator and an active seismic device like I-Pro 1
The two solutions differ in several respects, such as the operating mechanism and the method of installation.
- insulators are systems that, as the name implies, they isolate the structure at the base to avoid the transmission of the seismic action, by responding passively to the earthquake. They are installed between the foundations and the upper part building.
I active seismic protection systems, as the I-Pro 1 anti-seismic device, are smart technologies that They "react" to the earthquake, activating only in the event of a shock. By developing a modulated force based on the accelerations, they counteract and minimize oscillations. The I-Pro 1 active seismic heatsink is installed directly on the roof building.
Compared to seismic isolators, our active device features reduced installation and maintenance costs, because it does not require invasive interventions on the building and carries out a "self check”Weekly to constantly check their performance.
What are seismic isolators and how they work
As we mentioned, seismic isolators are passive systems that allow you to decouple the superstructure of the building by the motion of the ground, reducing the transmission of seismic energy.
I two main types of seismic isolators are:
- insulators elastomeric (possibly with lead insert)
- insulators scrolling (including those with sliding pendulum).
While the former are composed of steel plates alternating with layers of elastomer, the latter consist of two surfaces that slide over each other (curves in the case of the pendulum system).
A difference ofsliding pendulum isolator, I-Pro 1 is a dynamic technology which intervenes actively in countering the seismic forces, and is not limited to the re-centering and dissipative function passively implemented by the isolator.
Which system to choose?
Considering the characteristics of the two systems, which one to prefer? In which buildings to install the isolators? What about active devices?
- seismic isolators they are particularly suitable for the protection of public and strategic buildings (such as hospitals), of bridges and viaducts and historical-architectural heritage, because they allow to limit damage to the building and guarantee its functionality.
I-Pro 1 it is instead applicable on all small and medium sized buildings in reinforced concrete and steel, including the private homes. Being a flexible and non-invasive solution, it pays more seismic protection accessible of buildings, with reduced installation times. Furthermore, thanks to the sensors located on the building, I-Pro 1 allows a structural monitoring whenever you need it.
Seismic isolators and active devices can be used together in the same building: theintegration of the two systems increases the level of safety and guarantees even greater protection in the event of an earthquake.
I-Pro 1 is the intelligent active technology for the seismic protection of existing buildings.
