THE PEER-LIFELINES VALIDATION OF SOFTWARE USED IN PROBABILISTIC SEISMIC HAZARD ANALYSIS

Probabilistic seismic hazard analysis (PSHA) has become a fundamental tool in assessing seismic hazards and for estimating seismic design and seismic safety evaluation ground motions both on a site-specific basis for important and critical facilities and a national scale for building codes. A project to test and validate the numerical approaches and software used in PSHA was performed through sponsorship of the Pacific Earthquake Engineering Research (PEER) Center's Lifeline Program. A Working Group was organized and each member tested their own computer code in two sets of tests. Through several iterations, all codes were tested and acceptable answers were established either through analytical solutions or as the consensus answer from the test case results. The validation tests will be made available to any PSHA code developer/user worldwide through publications and the PEER website. The test cases will be used as a standard validation for all PSHA codes to be used in projects for the PEER Lifeline Program sponsors, which include the California Department of Transportation (CALTRANS), Pacific Gas & Electric Company (PG&E), and the California Energy Commission (CEC).
