• Abstract:
  Volume 2 focuses on a particularly complex and often misunderstood aspect of ground-structure interaction, which is ground yielding and loosening, and reports new findings in this area. The findings are based on previous research, on the knowledge gained during the development of the simplified analysis and the application of the more sophisticated finite element techniques, and on specific studies of strain softening ground behavior. A conceptual review of ground yielding behavior, including outlines of appropriate analytical treatments, is addressed in the report and emphasis is placed on the problematic phenomenon of loosening. In addition to providing some basic concepts of ground yielding, the report also describes and compares analytical solutions for plastic ground behavior. Finally, an analytical tool for treating strain softening behavior is provided. The authors point out that it is hoped that ground-yielding, and consequently, ground-structure interaction, can be better understood and analytically treated, even if some aspects remain somewhat problematic.
