Giax Tower
An innovative class A Eco-living project



The Giax Tower building is made up of a central body (tower) with surface area ~ 34x18m that extends 2 floors underground and 25 above ground, for a total height from the foundation of ~90m.

The tower, located at the center of the construction, is surrounding by two underground floors, intended for garages, and an above ground floor, intended for the gardens and pool.

The tower is separated from these surrounding floors by joints that restrict structural behaviour.

In the tower, the central stairs-lift-service shaft – made of reinforced concrete – is the structural element that ensure global building stability in both terms of horizontal stress resistance (seismic and wind) and top floor acceleration resistance (oscillation) due to wind, to guarantee safe “human comfort” for the occupants. The significant dimensions of the shaft and considerable wall thickness were set to secure the building against seismic actions and to reinforce it against wind, whose intensity increases with building height.

It should be noted that the seismic nature of the site (Milan) where the Giax Tower stands is rather limited and one of the lowest in Italy. This, however, does not exclude the chance of seismic waves, from even faraway epicentres, propagating in the foundation, stressing the building in ways perceptible to man. The special care with which this building was designed and constructed significantly limits the perception of consequent oscillations and guarantees total resistance and safety.

Tower floors, bi-dimensional plate type, are made with solid reinforced concrete slabs, 24 cm thick. These floors are secured to the reinforced concrete shaft and supported by columns made with special high-resistance steel profiles, specifically designed for multi-floored buildings, to ensure a contained floor section and constant solidity for the various floors. These floors, with their significant mass, significantly reduce noise transmission between one floor and the next. All structures were designed according to current Italian standards (Ministerial Decree 14/01/2008 – Technical construction standards), which, after the seismic events in recent years, have intensified the precautions to be adopted against seismic actions. For human comfort criteria in terms of limit accelerations and habitation conditions, reference was made to the National Research Council Instructions CNR-DT 207/2008.
