Title Retest of Thirty-Year-Old Neoprene Isolation Bearings.
Publication Date Mar 2014
Media Count 88p
Personal Author J. M. Kelly N. C. Van Engelen
Abstract A set of Neoprene isolation bearings remaining from a 1981 shake table test series conducted at the Earthquake Simulator Laboratory at the Earthquake Engineering Research Center (now the Pacific Earthquake Engineering Research Center) were retested in 2012. The new test series was conducted at the NEES site at the Richmond Field Station, University of California, Berkeley. The retest program had the dual purpose of determining the changes in the isolation properties, namely, the horizontal stiffness and equivalent viscous damping, and to study the behavior of the isolators at dynamic inputs that constitute beyond design-basis earthquake levels.
