The WUSTL American Society of Civil Engineering (ASCE) team of undergraduate students recently won the Best Overall Design Award, sponsored by Weyerhaeuser Co., in the National Timber Bridge Design Competition.
The WUSTL design consisted of a longitudinal, vertical-laminated, post-tensioned redwood deck over transverse stringers supported by steel rods suspended from a trapezoidal arch. This entry also placed first in Best Deck Design and first in Most Innovative Design.
The team received cash awards totaling $1,700 for its efforts, making it the top money-winner in the competition.
Twelve teams of students from universities across the United States matched wits in the competition.
Open to student chapters of ASCE and Forest Products Society, the competition was made possible by a grant from the U.S. Forest Service through its Wood In Transportation Program.
The Southern Pine Council of the Southern Forest Products Association, Unit Structures LLC, Wood Protection Products Inc. and Weyerhaeuser Co. provided additional financial support.
Each team designed, constructed and tested its bridge on its home campus, then submitted documentation of its activities and results to a panel of judges for review.
Each team was required to post design drawings, test results, and project highlights on the Web.
Dave Brakeman, adjunct professor of civil engineering, advised the team comprised of Kristen Erickson, Mark Hendel, Rob Hooper, Hamilton Hutchinson, Leah Martens, Robert Murphy, Dan Rieck, Steve Resnick and Stephanie Sheppard.
The bridge eventually was used at a nearby farm to traverse a small creek.
