This work presents a new semi-active friction damper device, based on piezoelectric technology, for the anti-seismic control of civil structures. The proposed device presents an original conceptual layout, characterised by a compact and easy allocation of the piezo actuator which is installed inside the piston of the damper. Theoretical performances were validated by means of experimental tests carried out on a physical prototype, loaded through a hydraulic test machine.
