(54)	Seismic shock absorber system and damping device for buildings with framed structure made of reinforced concrete

(57) This invention relates to a shock absorber System and Damping device designed to improve the strength against seismic action upon existing buildings with a framed structure made of reinforced concrete beams, columns and slabs, by means of anti-seismic dampers connecting one beam support from a particular floor to the base of the column on the next lower floor, where it rests on another end of the same beam inside each portal gap. (Fig.4).
Said system can also be adopted for new buildings.
Its area of utilization is that of anti-seismic building and rehabilitation of buildings.
