- Abstract
- Seismic base isolation is one of the most promising concepts in seismic resistant construction to come of age in this century. Most of the energy of an earthquake occurs at a period very near the fundamental period of low to mid-rise buildings. Base isolation reduces the response of the structures of this size to earthquake ground motions by shifting the structure's fundamental period away from the dominant period of the ground shaking. In an effort to facilitate the use of this technology, the National Institute of Standards and Technology (NIST) has published Guidelines for Pre-Qualification, Prototype and Quality Control Testing of Seismic Isolation Systems (NISTIR 5800, 1996).
