Izzat M. Idriss (1935-) is a Syrian-American geotechnical engineer. His research on the geotechnical aspects of earthquake engineering has led to the development of many of the currently used procedures for evaluating the behavior of soil sites and soil structures during earthquakes, such as methods for evaluating: the characteristics of earthquake ground motions; seismic response of sites; potential for soil liquefaction; performance of embankment dams during earthquakes; and soil-structure interaction in response to earthquake shaking.

Early Life and Education

Idriss was born in Qarah, a small village in Syria. When he was two years old his family moved to Damascus until he was 16, at which time he moved to Beirut, Lebanon to complete high school. In 1954 he moved to the United States to attend university.

He earned a BS Civil Engineering from Rensselaer Polytechnic Institute in 1958; an MS Civil Engineering from California Institute of Technology in 1959; and a PhD Civil Engineering from University of California, Berkeley in 1966 under the guidance of H. Bolton Seed.

Career

In 1960 he joined Dames & Moore at their New York Office and worked there until 1962, when returned to California begin his PhD at UC Berkeley. After earning his PhD, he was a member of the teaching and research staff of the geotechnical engineering group at the University of California, Berkeley (1967-1975). He began his work with Woodward-Clyde Consultants in 1969 while still at UC Berkeley, and continued working in Woodward-Clyde's San Francisco, Santa Ana and Oakland offices until 1989. In 1989, he joined the Department of Civil and Environmental Engineering at University of California, Davis, where he was also Director of the Center for Geotechnical Modeling (CGM) (1989–1996). He retired from UC Davis in 2004.

Learning From Earthquakes

Idriss has studied geotechnical data and damage impacts from damaging earthquakes to better understand the behavior of soils.[4] He studied L-Street slide in downtown Anchorage caused by the 1964 Alaska earthquake.[5] He used boring logs and SPT low counts from the 1964 Niigata earthquake to illustrate the use of the Seed-Idriss simplified liquefaction procedure.[6] A study of the 1967 Caracas earthquake evaluated the relationship between damage patterns and site conditions.[7][8]

After the 1989 Loma Prieta earthquake Idriss was appointed to the eleven-member Governor's Board of Inquiry, chaired by George W. Housner, which was formed to study the significant damage to bridges and freeway structures and to make recommendations about how to prevent such damage in the future.[9] Using strong motion records from soft soil sites, he analyzed site response at Treasure Island in San Francisco Bay, Foster City, and the San Francisco Airport.[10] [11]
