Revolutionary seismic protection

Protecting structures from earthquakes and aftershocks

The key features of the Tectonus system:

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

How it works

Overview

The joint consists of 2 outer plates and 2 cap 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 center slotted plates start to slide and energy will be dissipated through friction during cycles of sliding.
