The impact of a PEER funded project "Workshop - Liquefaction Susceptibility Modeling" is highlighted below. The project Principal Investigator (PI) is Armin W. Stuedlein, Professor, Oregon State University, Corvallis. The Co-Principal Investigators include Jonathan P. Stewart, Professor, University of California, Los Angeles and T. Matthew Evans, Professor, Oregon State University, Corvallis.
This workshop aims to follow in the footsteps of the 1996 NCEER and 1998 NCEER/NSF workshop on liquefaction triggering, and the 2016 NSF-funded US-Japan-NZ workshop on liquefaction effects to provide a set of consensus- based, short- and long-term recommendations for the improved evaluation liquefaction susceptibility and susceptibility modeling. This workshop should produce an immediate impact in the field of geotechnical earthquake engineering through cost- and risk-reduction practices through the adoption of uniform recommendations on liquefaction susceptibility evaluation. Furthermore, this workshop will allow for the improved development of a probabilistic liquefaction susceptibility model that can be seamlessly integrated into a probabilistic liquefaction-triggering model and within a performance- based earthquake engineering (PBEE) methodology.
