Part of: Structural Engineering in Natural Hazards Mitigation


A significant amount of research and development, shake table testing computer modelling and real world applications have been performed with the seismic isolation design concept in the past twenty years. Use of the technology is becoming more widespread since design codes have been adopted for bridges, buildings and hospitals. This paper documents the performance of three buildings and one bridge in California during recent earthquakes and provides a comparison with more extensive data collected in Japan.
