摘要

Thirty-two buildings from the Puget Sound Naval Shipyard (PSNS), Washington, USA, were seismicallyrnevaluated by the two-tiered evaluation recommended by the U.S. Federal Emergency Management Agencyrn(FEMA). The buildings, many of them large industrial shops and offices, were built between 1897 andrn1980 and represent a variety of building types with the largest category being steel moment framernstructure.rnThis paper presents the typical seismic deficiencies found during the evaluation and discusses the upgradernstrategies and the affiliated costs in relationship to building age, size, type, and historic classification. Thernpaper discusses the benefits and drawbacks of the seismic evaluation of large facilities, such as for PSNS.rnThe paper concludes that the seismic evaluation succeeds in identifying and quantifying the structuralrnupgrade needs of the buildings to full code performance levels, but does not address alternative solutionsrnthat consider partial upgrades or less severe performance goals to optimize upgrade works for thernavailable funding. It also concludes that, for owners of large facilities, the seismic evaluation alone doesrnnot offer a satisfactory basis for establishing upgrade priorities and implementation strategies withoutrndeveloping upgrade concept studies with affiliated cost estimates. The study found that the building agernand structural type are the most influential parameters on upgrade costs. Whether a building within thernsame age group is listed as historic or not, seems not to influence the upgrade costs. Similarly, a largerrnbuilding seems not less expensive to upgrade on a square foot price basis than a smaller building.
