Seismic isolators, once considered exotic and experimental, are now being installed in existing bridges and buildings to bring them to current standards. The article describes an award-winning project in Seal Beach, California where isolators were retrofitted in columns, and frames were strengthened in a building. Details of the isolation of the interior columns are described. Because seismic isolation is still outside the provisions of building codes, design and design checks required much effort and several months.
