A National Science Foundation sponsored workshop on the shear strength of liquefied soil was held at the University of Illinois at Urbana-Champaign on April 18-19, 1997. The workshop brought together approximately 25 leading researchers, consultants, and government engineers to discuss the important and controversial topic of the shear strength of liquefied soils. The workshop was organized to foster discussion in three main areas: theoretical and conceptual issues, laboratory and field measurement of the liquefied shear strength, and liquefied shear strength estimation from back-analysis of case histories. This paper presents a brief summary of the discussions of the workshop and the issues on which consensus were and were not reached. Specific consensus topics that were discussed at the workshop included terminology, laboratory versus field-based strength measurements, identification and characterization of field case histories, strength normalization using the initial vertical effective stress, fines content corrections/adjustments for field tests, reevaluation of liquefaction case histories, and future research needs.
