Abstract: The new $500 million Arrowhead Regional Medical Center in San Bernardino, Calif., sits near two fault lines. The importance of the facility and the sensitivity of the area made seismic design an integral part of the project. Using the building in a bathtub theory, the building is equipped with hundreds of dampers, isolators and absorbers all designed to curtail movement of the hospital during an earthquake. In addition, details in the piping and backup emergency systems should keep all the building's systems running for days, even if cut off from outside sources. The hospital is comprised of five buildings, which made some of the design tricky, but connections between buildings that allow horizontal and vertical movement should leave them undamaged.
