Abstract:
In the United States there are currently no widely
accepted standards for the testing and evaluation of
seismic base isolation systems for buildings, bridges
and ohter civil engineering structures. It is difficult
for designers to evaluate the characteristics of a given
system, or to compare competing systems, since standard
test methods and properties of systems have never been
clearly defined. This paper describes guidelines,
recently developed at the National Institute of
Standards and Technology (NIST), for testing and
evaluation of seismic isolation systems. The guidelines
are intended to apply to any type of civil engineering
structure. In this paper the philosophy behind the
development of the guidelines is first discussed. Then
the guidelines themselves are briefly reviewed, and the
three types of tests recommended by the guidelines are
described: pre-qualification, prototype, and quality
control testing. Finally, future research and standards
development activities related to the guidelines are
outlined.
