Training Class
Simplified SPT Performance-Based Assessment of Liquefaction and Effects
Description

Because of the many uncertainties involved in estimating hazards from liquefaction and its effects, traditional methods of analysis have been shown by many recent researchers to provide inconsistent and incorrect hazard estimates. Many of these inconsistencies come from the way that engineers incorporate probabilistic ground motions into their calculations. Probabilistic or performance-based analysis methods (akin to probabilistic seismic hazard analysis) are the most appropriate methods for incorporating probabilistic ground motions, but they can be difficult to implement on routine project because of their complexity. Fortunately, new research has developed simplified probabilistic approaches to analyzing liquefaction and its effects.

Objectives / Topics

The objective of this workshop is to introduce engineers to these simplified probabilistic approaches and to train them on using new tools developed for their implementation in design.

Six hours of theory and then end with a hands-on demonstration and practice of SPLiq (excel spreadsheet that performs the calculations).

Target Audience

Geotechnical engineers and engineering geologists that perform and/or review analyses related to liquefaction triggering, post-liquefaction settlement, lateral spread displacement, and seismic slope stability.

Prerequisites

Laptops will be provided.
