Troitsky Bridge Building Competition
Encyclopedia
The Troitsky Bridge Building Competition is an annual event that takes place at Concordia University in Montreal
, Canada
in the spring, during the National Engineering Week. Participating teams of engineering students come from universities across Canada
with some from the United States
and Europe
. They design and build model bridges out of popsicle sticks, toothpicks, white glue and dental floss.
Department of Sir George Williams University spoke with students in his bridge design class about building bridge models similar to those in their course work. Students then began building small-scale bridge models using wood and glue.
By 1984, the department had become the Department of Building, Civil and Environmental Engineering (BCEE) of Concordia University and held the First Annual Bridge Building Competition. Initially, the contest was only open to Civil Engineering students enrolled at Concordia. Later the event expanded to include other universities in the province of Quebec, then those across Canada. In 1991, the competition included its first international teams, from the United States.
In 1988, the Civil Engineering graduating class created an award for most innovative concept, and dedicated it to the memory of Lars Rowland, an alumnus who completed his B.Eng in 1988 at Concordia and was working as a civil engineer for Canadair
when he died in 1990 piloting his plane. The inscription reads:
The Crusher, the hydraulic press which tests the strength of each bridge and is the focal point of the competition, has a history of its own. The original Crusher was a hydraulic device which, after ten years of service, was damaged beyond repair in 1994 - exploding hydraulic fluid
all over the judges and competitors while attempting to crush the truss-bridge designed by Hugues Rivard, who was a Masters student at BCEE. A mark remains on the ceiling of the Hall Building Alumni Auditorium from the incident, and the real capacity of Rivard's bridge remains a mystery. The next Crusher was a donation from Wainbee in 1994. It was a screw jack style mechanism controlled by a computer. It could apply loads of up to 6000 pounds. In 2000, Mechtronix Inc. donated a new Crusher, which has a 10-ton capacity. During the 2000 competition, a bridge resisted up to 1860 kgf. The winner, however, is the one that has the highest overall score in terms of capacity, esthetic value, and originality. For the 2010 competition a brand new crusher donated by Concordia's department of Building, Civil, and Environmental Engineering and is follows its origins and is again a hydraulic jack.
