Title: Reduced-Scale Elastomeric Seismic Isolation Bearing Tests
Author(s): Rodney H. Holland
Publication: Special Publication
Appears on pages(s): 1259-1275
Keywords: Bearings; bonding; earthquake-resistant structures; tests.
Abstract:Using a new bearing production technology, scalable, six inch seismic isolation bearings were built to accurately represent many characteristics of full-scale 24 to 36 inch bearings, including elastomer properties, bearing shape factor, metal layer stiffness and total elastomer height-to-width ratios. Test methods for quarter-scale bearings and components are reported that provide reliability and ultimate strength data. Because reduced-scale tests cost less, larger numbers of relevant tests can be conducted in the development stages of bearing design, thereby reducing overall development costs and increasing reliability.
