DEVICE, SYSTEM AND METHOD FOR INCREASING THE EARTHQUAKE RESISTANCE OF BUILDINGS

WIPO Patent Application WO/2014/041525

A3

A device (1) for increasing the earthquake resistance of a building comprises elements (2A.2B) subjectable to elasto-plastic deformation and having at least one hollow member (8A,8B) intended to be deformed along a predetermined axis of deformation (D2) and which can be constrained in use to an upright column (C) and to a crossbeam (T) positioned on the upright column (C) slidably at least along the axis of deformation (D2), the elements (2A.2B) subjectable to elasto-plastic deformation being configured in such a way that, in use, the at least one hollow member (8A,8B) can be compressed and deformed elastically along the predetermined axis of deformation (D2) as a result of a displacement of the crossbeam (T) on the column (C) up to a first predetermined displacement value, and can be compressed and deformed plastically and irreversibly along the predetermined axis of deformation (D2) as a result of a displacement of the crossbeam (T) on the column (C) greater than the first predetermined displacement value in such a way as to absorb energy deriving from the action of the earthquake, thus limiting the displacement of the crossbeam (T) on the column (C).
