Simplified SPT Performance-Based Assessment of Liquefaction and Effects

The objectives of this project are: (1) Derive new simplified performance-based procedure for liquefaction triggering, lateral spread displacement, free-field post-liquefaction settlements, and Newmark seismic slope displacements.(2) Develop liquefaction parameter maps in geographic information system (GIS) format associated with each of the hazards included in objective 1 at return periods of 475 years, 1033 years, and 2475 years for each of the states participating in the study. (3) Evaluate the new simplified performance-based liquefaction procedures against conventional (i.e., American Association of State Highway and Transportation Officials (AASHTO)) liquefaction analysis procedures. (4) Develop a simplified design procedure that will allow the designer to envelope the performance-based and conventional results to select which result will govern the design.
