DFI Educational Trust Student Paper Competition

GIGSO alumnus, and recent Oregon State M.S. graduate, Youssef Bougataya was selected as the winner of the Deep Foundations Institute (DFI) Educational Trust 2016 Student Paper Competition. Youssef's paper, titled "Region Specific Calibration of Resistance Factors for Use with Static and Wave Equation Analyses of Driven Piles", can be found in a future issue of the DFI Journal, and more information on the achievement may be found here.

 

Tunneling Short Course

On June 20-23, 2016, GIGSO member Stephie Lange had the opportunity to attend a short course, titled "Tunneling Fundamentals, Practice, and Innovations", at the Colorado School of Mines. The course provides a setting for experts in the tunneling field to share knowledge with industry professionals, and is offered on an annual basis. Stephie has been kind enough to write up a summary of her experience, which can be found by following this link.

 

GeoPrediction 2016

Our club is pleased to announce that the prediction of master's student and GIGSO member, Youssef Bougataya, and undergraduate senior, Nathan Jones, has won the prestigious Mohr's Circle trophy by placing first in the 2016 Geo-Institute GeoPrediction competition. More details on this year's project, and competition rules, can be found here, while a nice writeup by the College of Civil and Construction Engineering may be found here.

 

6th International Conference on Earthquake Geotechnical Engineering

On November 1-4, 2015, the city of Christchurch, New Zealand hosted the 6th Interntional Conference on Earthquake Geotechnical Engineering. Participants from Oregon State University were GIGSO members, Stephie Lange and Kengo Kato, as well as College of Engineering Dean, Scott Ashford, and School of Civil and Construction Engineering faculty, Michael Olsen, Armin Stuedlein, Ben Mason, and Daniel Gillins. Stephie has provided a summary of her experiences at the conference, and New Zealand in general, which can be found by following this link.

 

Mohr's Circle Trophy! Congratulations to Andrew Strahler and Trevor Bineham

Andrew and Trevor received first place at the GeoPrediction Competition at Geo-Congress 2014!  They most accurately predicted results from a geotechnical case history.  Andrew and Trevor presented their results to conference attendees and produced a poster describing their award winning analysis. Overall 26 international teams were involved in the competition for this years Geo-Congress conference held in Atlanta, Georgia.

Andrew and Trevor would like to thank Dr. Armin Stuedlein, P.E., their graduate and undergraduate classmates, reviewers, OSU CCE and everyone else typically thanked by Hollywood award winners (with a Corvallis alpha angle of inclination of course).

Deep Foundation Institute 2013 Young Professor Paper Winner

Congratulations to Dr. Stuedlein, P.E. on winning the Deep Foundation Institute 2013 Young Professor Paper Competetion!  Our own Seth Reddy, Ph.D candidate, provided his humble assistance as well.

 

Improvements to the Graduate Geotechnical Laboratory                                               

Geotechnical professor, Matt Evans, Ph.D. has been heading up extensive upgrades and additions to the Graduate Geotechnical Laboratory along with Daniel Simpson ...

The Instructional Lab Space within OSU's Graduate Geotechnical Lab has undergone a large transformation over the last 6 months. New additions include direct shear, stress & strain controlled load frames, constant rate and incremental loading consolidation, microscopic imaging, and fall cone apparatus.
