DEVELOPMENT OF A NEW SEMI-ACTIVE FRICTION DAMPER USING PIEZOELECTRIC TECHNOLOGY FOR THE ANTI-SEISMIC CONTROL OF CIVIL STRUCTURES

Abstract

This work presents a new semi-active friction damper, based on the piezoelectric technology, for the anti-seismic control of a civil structure. The device has been conceived and designed at D.I.A.S. (Department of Aerospace En­gineering) of University Federico II of Naples. It belongs to the family of the semi-active technologies of structural control for a civil structure. Damper is based on an external cylinder and an internal hollow piston that slips in­side the cylinder. Device presents an original conceptual lay-out, developed at D.I.A.S and it is independent by any scheme, available in literature.
