Abstract
Friction-Damped Moment-Resisting Frames are discussed as an alternative to steel ductile moment-resisting frames. The design involves replacing all full penetration welds with bolted friction connections, thereby eliminating the problem of failures at welded connections as exhibited during the Northridge earthquake. Energy dissipation is achieved at the friction interface in lieu of inelastic behavior of the frame. Analytical methods that perform an energy accounting are discussed.
