- Sixty-seven engineers, geologists, geophysicists, and seismologists from the United States and abroad participated in the workshop to discuss the current state of dynamic soil property measurement and site characterization for earthquake-resistant design and analysis, and to explore ways to achieve necessary advances and identify research priorities. The workshop addressed six key technical topics, including low- and high-strain cyclic soil material properties, mechanisms for energy dissipation, spatial variability of soil properties, effect of site geometry and global characteristics, seismic arrays, and sloping ground sites. Experts determined that the highest priority research need industrywide is development and operation of field test sites for site soil characterization and method validation in seismically active areas. Other research needs exist in the following areas: technology enhancement of soil in situ and laboratory testing; investigation of physical-chemical processes affectiing property changes; sensitivity evaluation of dynamic soil property variations; and improvements in data processing methods, field data interpretation techniques, and ground-response modeling procedures.
