Two sections of road 鈥� a bridge girder and diaphragm 鈥� that were affected by
the tractor-trailer fire and subsequently collapse of Interstate 95 will be
housed at 91制片厂鈥檚 College of Engineering beginning this week,
offering researchers and students alike a unique chance to learn from the
incident.
Arvin Ebrahimkhanlou, PhD
, assistant professor and
Amir Farnam, PhD
, associate professor of civil, architectural and environmental engineering,
collaborated with officials at PennDOT to secure the sections, which come
from a section of the elevated road that was closes to the fire. They say
that the housing of the sections will open doors to a variety of academic
opportunities.
鈥淔rom a research perspective, by looking at the deformed girder, we will be
able to assess its condition,鈥� Ebrahimkhanlou said. 鈥淭his will provide
valuable visual clues that can help machine learning-based visual
inspections recognize when a bridge is at risk.鈥�
Farnam added that the section could be used for materials research. 鈥淭here
is still concrete and rebar attached to the girder,鈥� he said. 鈥淲e can look
at samples on a microscopic level to determine their material makeup and how
the fire affected them, giving us insight into what compositions can
withstand what temperatures.鈥�
The sections will also act as a powerful teaching tool for undergraduate
students.
鈥淵ou don鈥檛 typically get to see a massive piece of road like this,鈥�
Ebrahimkhanlou said. 鈥淪tudents from across the college will get a chance to
see the damage up close, leading to conversations among structural engineers
about how the bridge was designed; among architectural engineers and
materials scientists about what was used to build it; and among civil
engineers about the impact on traffic, commerce, the local neighborhood, and
so on.鈥�
Drexel engineers have been keeping tabs on the I-95 project since the
morning of the collapse. Experts from the college have been
providing context
to the incident and rebuilding project in local media, and Aero Aggregates
of North America, a company under the direction of alumnus Archibald S.
Filshill, MS civil engineering 鈥�95, PhD civil engineering 鈥�10, provided
for the backfill project.
