Maurer AG has successfully completed the first phase of full-scale testing of the new MAURER SHARK® hysteretic damper. The device is designed to absorb seismic energy and protect load-bearing building structures in high seismic activity zones.

Operating Principle

MAURER SHARK® uses the principle of hysteretic energy dissipation: under seismic loading, a specially designed element made of high-ductility steel deforms, absorbing oscillations and preventing their transfer to the load-bearing elements of the building.

The new generation of dampers provides 40% greater energy absorption compared to previous designs at comparable device dimensions.

Test Results

  • Maximum test load — 2500 kN
  • Number of loading cycles without degradation — over 50
  • Operating temperature range: −40°C to +70°C
  • Compliance with EN 15129 and AASHTO confirmed

Testing was conducted on a certified test rig in Munich. During the 12-week cycle, the device was subjected to loads exceeding the design seismic effects of a magnitude 9 earthquake.

Applications

The damper is designed for use in seismic isolation systems for residential and public buildings, bridges, and industrial structures. The development is particularly relevant for construction in Central Asia — a region of high seismic activity.

MAURER SHARK® devices have already been included in the design documentation for several projects in Kazakhstan and Kyrgyzstan scheduled for construction in 2026.
