Development and Use of Seismic Shock Test Criteria for Essential Equipment in Critical Facilities.
Abstract
This report provides procedures for establishing seismic qualification test criteria for essential equipment in critical facilities and presents guidance for interpretation of the test results. Since equipment representative of that used in the essential systems of critical facilities was observed to be closely related to many items of tactical support equipment used at missile sites, existing data from proof and fragility tests on tactical support equipment were reviewed to analyze failure characteristics. The failure data were organized so they could be statistically analyzed to provide estimates of the probability of failure. The major tasks in the seismic test qualification of equipment are summarized; these tasks include test criteria formulation, test facility selection, test unit formulation, establishment of test qualification requirements, and interpretation of test results. Test criteria were developed by: (1) test axis selection, (2) statement of operating configuration, (3) definition of expected failure modes, and (4) description of the shock environment which can be transformed into a time history waveform to drive a shake table. Methods for developing waveform test criteria from the output of various types of dynamic building analyses are presented. Requirements for reporting and documenting test results are also discussed.
