What started almost a century ago as buffer between railway cars has now become a universally applicable damping element for almost all industry sectors – also as a protective element against potential damages to buildings and industrial facilities caused by earthquakes.
The 9th International STESSA Conference on the Behaviour of Steel Structures in Seismic Areas took place from February 17 to 19 in Christchurch (New Zealand). This conference, which is triennially held, is organized by the Steel Construction New Zealand Incorporated (SCNZ) in cooperation with the University of Auckland, the University of Canterbury and the University of Naples. Like the previous STESSA Conferences, the University of Canterbury was selected to host this event.
This year, the 15th D-A-CH Conference, which is organized by the Societies of Earthquake Engineering and Structural Dynamics in Germany (DGEB), Austria (OGE) and Switzerland (SGEB) took place on September 21 and 22. September.
This gathering of experts is conducted biennially and serves both as the exchange of knowledge between seismologists and engineers and the presentation of current scientific findings and experience gained from field applications. In addition, companies operating in the fields of earthquake engineering and structural dynamics as well as manufactures of earthquake protection systems had the opportunity to present their application solutions in the foyer of the Bauhaus university.
If buildings are shaken by earthquakes this can lead to cracks, instabilities in the support structure and in worst case szenarios to the collapse of the building. To efficiently absorb the enormous forces and thereby protect both, person and material, nowadays sophisticated technologies are available.
Not all damages that a great earthquake will cause can be avoided. However, with Friction Springs there is a very high probability, that the building withstands an earthquake – like those in Christchurch/NZ in 2010 and 2011 – and is still operational and habitable.
