Revolutionary seismic protection

tectonus platform technology

resilient Slip Friction joint
(RSFJ)

  • Dissipates earthquake energy
  • Restores the structure after each seismic event
  • No sacrificial components
  • No post event maintenance required

COMPACT DESIGN & powerful function

COMPONENTS:
HIGH STRENGTH BOLTS
DISC SPRINGS
CAP PLATES
CENTRE PLATES WITH ELONGATED HOLES
The RSFJ is assembled and prestressed to specification.
Depending on the configuration, it can be designed to withstand up to 1000kN. Options beyond this are also possible.

How it works

sELF CENTRING every time

Earthquake forces are absorbed by the RSFJ connection through friction.
As the RSFJ plates slide and dampen the seismic energy, they will protect the structural integrity of the building - always returning to their original position.

lIMITLESS POSSIBILITY

Freedom to design. With any flag shape.

The RSFJs compact and scalable configuration offers design freedom for any application.

The compact joint is exceptionally scalable and can be implemented in all types of projects  of various materials and configurations.
