Seismic Tests of Friction Damped Steel Frames

Document Type: Proceeding Paper

Part of: Dynamic Response of Structures

Abstract:

This paper presents the results obtained from qualification tests of a new friction damping system, which has been proposed in order to improve the response of Moment Resisting Frames and Braced Moment Resisting Frames during severe earthquakes. The system basically consists of a special inexpensive mechanism containing friction brake lining pads introduced at the intersection of frame cross-braces. Seismic tests of a three storey Friction Damped Braced Frame model were performed on an earthquake simulator table. The experimental results are compared with the findings of an inelastic time-history dynamic analysis.
