This proceeding presents cutting-edge information in active research and practical interest in the field of soil dynamics and geotechnical earthquake engineering. The topics include methods for liquefaction assessment, constitutive modeling, cyclic shear strength, dynamic soil-structure interaction, dam engineering, soil improvement, in situ testing, and probabilistic methods. From discussion of these topics, you will see how combinations of modern computational methods and experimental research can help to advance the understanding of both fundamental and applied problems.
