Apparent-Weakening in a Quarter-scaled Isolated Bridge
|
DOI:10.4231/D3000007H
Experiment Type: Shake Table
Description: The Negative Stiffness Devices, which were modified in the previous experiment, were implemented inside a quarter-scaled highway bridge model and were tested experimentally for many shake table tests of different ground motions with different scales and configurations and their performance were compared with elastomer bearings and viscous dampers.
