Abstract: This paper provides an overview of the various structural engineering tasks that are associated with the implementation of the design of a seismically isolated structure. The project is an eight-story, 320,000 s.f. steel braced frame structure which utilizes a combination of lead-rubber and elastomeric bearings for the seismic isolation system. The project is currently in the final stages of back-check with the California Office of the State Architect. The design process for this project is outlined as: preliminary assessment of the feasibility of the use of seismic isolation; establish design criteria & plan check review procedure; select seismic isolation scheme, seismic isolation consultant & supplier; analysis/design; and plan check/review.
