Experimental Needs for Geotechnical Earthquake Engineering. Report of a Workshop. Held in Albuquerque, New Mexico on November 4-5, 1991.
National Science Foundation, Washington, DC., January 1991, 234 p.
Geotechnical factors have a major influence on the performance of almost every civil engineering structure in an earthquake. The importance has been demonstrated by catastrophic or near catastrophic failures during major earthquakes over the past 30 years. Significant attention to geotechnical issues began after the extensive liquefaction in the 1964 Niigata, Japan earthquake, the catastrophic landslides and ground failures in the great Alaskan earthquake of the same year, and the near-failure of two critical earthdams in the 1971 San Fernando earthquake. Soil-structure interaction effects on the behavior of nuclear power plants in earthquakes have been a major source of uncertainty. The overall objective of the workshop was to provide an evaluation of current experimental needs for geotechnical earthquake engineering and current capabilities to support those needs.
