A Study of a Hardening Type Friction Damper

In this paper, a friction damper that has resisting force characteristics of hardening type and returning to the original position was proposed. The friction damper is composed of stacked two sets of V-shaped links, coil springs, brake shoes, a load column, outside and inside frames. The resisting force characteristics of the damper, and the frequency and seismic responses of a single-degree-of - freedom system supported with the damper were analyzed. The trial damper was made, and the resisting force characteristics and the effects of vibration suppression of the damper were substantiated experimentally and numerically.
