Momentum connectors

The aim of the project is the development of sensor-controlled, ultra-high-performance momentum connectors with high energy dissipation potential for indestructible high-rise buildings in earthquake areas.

In order to achieve the development goal, the following target parameters are being pursued:

The connection should

  • be able to absorb forces which occur in standard multi-story buildings (at least 5 stories),
  • be indestructible under stresses resulting from earthquakes,
  • exhibit no changes in properties, even after repeated, multiple loading,
  • be controllable,
  • be easy to use, so that an anticipated higher material price can be compensated through a lower installation outlay,
  • be employable in load-bearing structures made from steel, wood, concrete and possibly other materials and
  • be adaptable to the respective engineering requirements as necessary.
