ESWP: International Bridge Conference®: Student Scholarships
JAMES D. COOPER STUDENT PAPER COMPETITION
The 2008 James D. Cooper Graduate Student Award is awarded to:
Woo Soek Kim of the Pennsylvania State University for his paper entitled: Simplified Nonlinear Numerical Method for Integral Abutment Bridges.
Abstract of the winning paper:
Many engineering uncertainties exist in the prediction of long-term behavior of integral abutment bridges (IABs). This paper reports simplified numerical modeling methodologies regarding thermal and time-dependent loads based on field monitoring of IABs on the I-99 corridor. Measured and predicted response indicates that IAB loads, i.e., soil-structure interaction, and superstructure time-dependent effects by means of concrete creep, concrete shrinkage, and prestressing strand relaxation are significant factors influencing long-term IA bridge behavior. In addition, relatively low rotational stiffness of abutment-to-backwall connections influences soil-structure interaction and time-dependent effects, resulting in an increased long-term response over the short-term response. The developed numerical model simulates the nominal IAB behavior and response and therefore, provides the basis of long-term and/or probabilistic numerical simulation.
The 2008 James D. Cooper Undergraduate Student Award is awarded to:
Heidi Clayville, Theresa Howell and Kristen Erickson of Washington University in St. Louis for their paper entitled: The New Daniel Boone Bridge Project: US Route 40/I-64 Across the Missouri River.
Abstract of the winning paper:
Interstate 64 (U.S. Highway 40) currently has two bridges known as the
Daniel Boone Bridges crossing the Missouri River in Chesterfield, Missouri.
The westbound structure J1000R, was opened in 1935 as a two-lane, bi-directional
bridge. Currently it carries three restricted width lanes with no shoulders.
The eastbound structure, A4017, was opened in 1990 as a two-lane bridge
and currently carries three lanes with nominal shoulders. The owner of
these two bridges, the Missouri Department of Transportation (MoDOT) desires
to add additional lane capacity to this crossing to relieve daily congestion.
MoDOT has evaluated the corridor’s current and projected traffic
needs, safety, condition of the existing bridges, effects to the natural
and human environments as well as public involvement. The current and
projected traffic volumes require three lanes, an auxiliary lane, and
full shoulders in each direction. To satisfy these needs an additional
structure is needed. A study team has examined the effects of a new river
crossing on environmental factors such as natural resources, wetlands,
archaeological sites, and agricultural, public and private land use. After
several years of engineering work and a public environmental process the
Missouri Highways Transportation Commission (MHTC) approved the location
for the additional bridge that will connect St. Charles and St. Louis
counties. The approved design will provide a new four-lane bridge over
the Missouri River upstream of the existing bridges to carry eastbound
traffic. The existing eastbound bridge, A4017 will be re-striped to carry
westbound traffic and the existing westbound bridge, J1000R will continue
to carry westbound traffic.
