RSFJ Technology

Resilient Slip Friction Joint

The RSFJ

The Resilient Slip Friction Joint is a unique and innovative joint that improves seismic resilience of structures.

The RSFJ has the capacity to dissipate earthquake energy and restore a structure after both primary and aftershock seismic events.

How it Works

The RSFJ consists of 2 outer plates and 2 centre plates with elongated holes. The outer plates and the centre slotted plates are grooved and clamped together with high strength bolts and disc springs. When the applied joint force overcomes the frictional resistance between the sloped bearing surfaces, the centre slotted plates start to slide and energy will be dissipated through friction during cycles of sliding.
