Abstract

Viscoelastic dampers to reduce building structural vibration were first utilized in the Twin World Trade Center Towers in New York in 1969 for wind induced vibrations. In the 1980s, the Columbia SeaFirst and Two Union Square Buildings in Seattle utilized dampers for wind. In 1994 the Chien-Tan railroad station roof in Taipei, Taiwan utilized viscoelastic dampers to reduce wind induced vibrations. Recent seismic studies at several universities have demonstrated the benefits of viscoelastic dampers for steel and concrete structures. A 13 story steel moment frame building in Santa Clara County was retrofitted with viscoelastic dampers in 1994 to reduce seismic vibrations. A non-ductile concrete building in San Diego will be retrofitted with viscoelastic dampers in 1996. The results of university testing and building application installations are reviewed in this paper.
