Issues Related to the Selection of U.S. Navy Buildings for Base Isolation
Abstract
Major structural engineering advances in the area of earthquake engineering have taken place with increased frequency since the 1971 San Fernando earthquake. Advances include: (1) Steel detailing for reinforced concrete buildings, (2) Ductile design criteria for reinforced masonry shear walls and, (3) Eccentric bracing of steel frames. One major advance has been the introduction of shock isolation concepts into building design and this advance is commonly referred to as Base Isolation. As with any new development, there are many proposed variations which more or less seek to satisfy the same objective. Some base isolation schemes are simple, well considered, and supported by both theoretical and dynamic experimental research. Others are not developed sufficiently to trust their use where U.S. Navy lives and operations are at risk. Keywords: Seismic design; Base isolation; Structural response; Quality control; Ground motion; Torsion.
