2020 Paper Competitions Winners
The 2020 winners of DFI's Young Professor and Student Paper
Competitions presented their papers during DFI's 45th Annual Conference on Deep Foundations in October.

Young Professor Winners
The young professor winners were Alejandro Martinez, Ph.D.,
assistant professor, and Kyle O'Hara, Ph.D., graduate student
researcher, University of California, Davis. They presented their
paper, " Applications of Frictional Directionality for Monotonicallyand Cyclically-loaded Piles, " which describes the load-transfer
behavior of piles with surface inspired by the belly scales of snakes
that mobilize a direction-dependent skin friction. Test results are
shared in the paper, which covers the potential benefits that the bioinspired surface texture could realize on the overall performance of
axially loaded piles.
Aaron Gallant, Ph.D., P.E., and Danilo Botero-Lopez, research
assistant, University of Maine, received a special recognition award
for their paper, " On the Basal Stability of Embankments Supported
on Fractured Unreinforced Rigid Columns Over Soft Soils. "

Student Winner
Rabie Farrag, Ph.D., student researcher, University of California,
Irvine, was the student winner for his paper, " Experimental
Investigation of Shear Demands on Rock Socketed Drilled Shafts

Alejandro Martinez

Kyle O'Hara

Rabie Farrag

Subjected to Cyclic Lateral Loading. " This paper presents an
experimental research program of three large-scale, fully
instrumented drilled shafts with different transverse reinforcement
ratios that studies the lateral load transfer of rock-socketed drilled
shafts subject to cyclic loading until complete structural failure. It
evaluates current design recommendations for piles with rockbased tip fixity.
DFI and the DFI Educational Trust hold the Young Professor and
Student Paper Competitions annually to help bridge the gap
between practice, studies and research. The 2020 winners receive
free conference registration, a library of up to 20 printed DFI publications and a complimentary two-year DFI Individual Membership.
The Call for Abstracts for the 2021 Paper Competitions are now
open. Visit the 'Awards and Lectures' page at www.dfi.org for more
information.
