This paper presents a case study life cycle analysis of a conventional and base isolated steel braced frame office building. The case study focuses particularly on the effects of moat wall pounding and business interruption using the FEMA P-58 methodology. Analytical results suggest that the overall performance of the base isolated building is far superior to the conventional building but that expected financial losses in the isolated building become significant if structural pounding occurs. The cost-effectiveness of the isolation is found to be particularly sensitive to the ability of businesses to relocate quickly and effectively after a large earthquake.
