Structural protection system for buildings

Abstract

A structural protection system of buildings is described, comprising at least one bearing structure ( 2 ) connected with at least one wall of said building (E). The bearing structure ( 2 ) is rigidly connected to the wall of the building (E) and the bearing structure ( 2 ) is a specialized structure comprising an energy dissipation device ( 1 ) adapted to dissipate the energy generated by the oscillations of the bearing structure due to earth tremor.
