Presentation Title: Earthquake behavior of Geosynthetic Reinforced wall retaining structures

  1. Erol Guler, Ph.D., Professor
  2. Professor, Bogazici University, Turkey

Dr. Erol Guler is a full professor of geotechnical engineering at Bogazici University, Istanbul, Turkey since 1989. He acted as the Director of Environmental Sciences Institute of Bogazici University between 1996 and 1999 and as the Chairman of the Civil Engineering Department between 2004 and 2010. He was a visiting Fulbright Professor at the University of Maryland between 1989 and 1991. Prof. Guler is the leading geosynthetic scientist in Turkey, having been an IGS Member since 1989. He founded the IGS Turkish Chapter in 2001 and served as its president until 2005, and was reelected as President again in 2011. He was the organizer for the first two national geosynthetic conferences in 2004 and 2006 and is currently the chairman of the organizing committee of the 2016 European Regional Conference of IGS, EuroGeo6. Prof. Guler has been a member of the International Standards Organization (ISO) Technical committee on geosynthetics as a representative of the Turkish Standards Institute since 2002. He is currently the Convener of the WG2 of ISO/TC221 (Technical Committee on geosynthetics) and is also the Convener of the WG2 of CEN-TC189 (European Committee for Standardization’s Technical Committee on geosynthetics). Prof. Guler is currently an international member of the USA TRB Committee on Geosynthetics. Prof. Guler’s research has focused mainly on geosynthetic reinforced walls and specifically he conducted research on the use of marginal soils in such structures and their behavior under earthquake loading conditions. His research work includes numerical studies as well as shaking table tests and full scale tests. In addition to his research work, Prof. Guler has extensive practical experience, including design work for numerous projects where geosynthetics were used as reinforcement or liners.
