Simplified SPT Performance-Based Assessment of Liquefaction and Effects: Tasks 1 and 2

The purpose of the research being performed is to provide the benefit of the full performance-based probabilistic earthquake hazard analysis, without requiring special software, training, and experience. To do this, simplified models of liquefaction triggering and lateral spread displacements that approximate the results of the full probabilistic analysis were developed. This report provides the derivation and validation of these simplified models, addressing Tasks 1 and 2 of the TPF-5(296) research contract. These simplified procedures are based on retrieving a reference value from a hazard-targeted liquefaction parameter map and calculating site-specific correction factors to adjust the reference value to represent the parameter for the site-specific soil profile. Site-specific values calculated using the simplified method are compared to those calculated using a full probabilistic method for ten cities in the United States. The difference between the full and simplified procedures for both liquefaction triggering and lateral spread displacement models is shown to be within an acceptable amount. This shows that the simplified procedures derived in this report can reasonably approximate the results of a full probabilistic procedure.
