Purpose and Background

These presentations were recorded at the 2024 GI Web Conference.

Analyses of LEAP 2020 Experimental Results and Validation of Numerical Predictions (2 hours)

The current landscape of geotechnical engineering benefits from abundant computational power and advanced numerical modeling platforms capable of analyzing the dynamic response and liquefaction of saturated granular soil systems. In this regard, an important step is the validation of soil constitutive models and modeling platforms to foster a greater acceptance and utilization of numerical modeling in geotechnical engineering design and analysis. Recent efforts under the Liquefaction Experiments and Analysis Projects (LEAP) are aimed at promoting the validation of numerical models developed for soil liquefaction. LEAP is a series of international research collaborations aiming to produce high quality experimental data to validate soil constitutive models and modeling techniques for dynamic geotechnical systems involving soil liquefaction. The focus of this web conference is to present the analysis of the LEAP 2020 experimental data and a validation methodology for numerical simulations of geotechnical systems involving soil liquefaction using centrifuge experimental data

Benefits and Learning Outcomes

Upon completion of these sessions, you will be able to:

• Explain the importance of validating soil constitutive models and numerical modeling platforms for analyzing the dynamic response and liquefaction of saturated granular soils.
• Describe the goals and significance of the Liquefaction Experiments and Analysis Projects (LEAP) in advancing numerical modeling validation for geotechnical systems.
• Identify the key steps involved in the validation methodology for numerical simulations using LEAP 2020 centrifuge experimental data.
• List the benefits of international research collaborations, like LEAP, in producing high-quality experimental data for the geotechnical engineering field.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

This course is worth 0.2 CEU/2 PDHs. To receive your certificate of completion, you will need to complete a short post-test online and receive a passing score of 70% or higher within 365 days of course purchase.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
