Seismic isolation systems designed according to the 1991
"Uniform Building Code", or the 1991 AASHTO "Guide
Specification for Seismic Isolation Design" are required
to undergo a series of prototype and quality control
tests before being installed in the structure. At the
present time standards do not exist for conducting these
tests and results are subject to unknown variability.
The document represents the initiation of the process to
develop standards for quality control testing of seismic
isolation systems built in the U.S. The guidelines are
devoted specifically to quality control testing of
elastomeric systems. The guidelines address material
and component tests to be conducted during production,
and tests on completed isolation units. Nine production
tests are specified in the guidelines. Three completed
isolation unit tests are outlined: sustained
compression, compression stiffness, and effective
stiffness and energy dissipation. Complete details of
the test set-up, test procedure, data acquisition,
analysis and reporting of results are given in the
guidelines. Performance criteria are established for
all tests, systems that do not meet these criteria may
not perform satisfactorily in service and should be set
aside for disposition by the engineer of record.
