- In order to determine the effectiveness of adding viscoelastic dampers to structures on the reduction of their seismic response, a comprehensive analytical and experimental program was carried out. The experimental program was first conducted on a 2/5-scale five-story steel frame under precisely controlled ambient temperatures and subject to simulated ground motions with peak accelerations ranging from 0.12g to 0.60g. Results show that viscoelastic dampers are very effective in attenuating seismic structural response at all levels of earthquake ground motions, and that their energy dissipation capacity decreases as ambient temperature increases. However, they are effective at all temperatures tested in the research program.
