Revolutionary seismic protection
With unlimited design potential
Resilience meets elegant design
The RSFJ technology
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 center plates with elongated holes. The outer plates and the center 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 center slotted plates start to slide and energy will be dissipated through friction during cycles of sliding.
