Damper Modelling and tests
Damptech has developed and tested dampers from 100kN (22.5 kips) to 5000 kN (1124 kips)
The 5000 kN damper shown below is one of the largest capacity dampers in the world, and was developed for the earthquake protection of the Abenobashi Terminal Building, the tallest building in Japan at 300 m, which opened on March 7, 2014 in Osaka.
Advanced Finite Element Models have been created of the large capacity dampers that have been tested. The numerical results from the damper models are virtually identical to the results obtained experimentally, due to the predictable and reliable patented rotational friction design.
