MIT Steel Bridge Team takes second place at national competition

The 2012 MIT Steel Bridge Team with its bridge.


The MIT Steel Bridge Team — sponsored by the Department of Civil and Environmental Engineering — placed second at the 2012 National Steel Bridge Competition, out-engineering 45 other teams that had been winnowed from 200 in regional contests. The University of California, Berkeley, took first place at the event, which was held Memorial Day weekend at Clemson University.

The annual contest requires student teams to design an approximately 20-foot scale model of a bridge for a hypothetical site that meets specifications outlined in a request for proposals. Teams must fabricate steel pieces to build the bridge and during the competition, be able to assemble it very quickly. The rules are rigid, reflecting the safety needs and landscape characteristics of an actual site. Bridges must be able to withstand a 2,500-pound load without sagging; a deflection of more than one centimeter, for instance, might be considered too large.

This year’s scenario called for a cantilevered bridge (one end of the structure must extend beyond the supports) to span the imaginary Phantom River, providing access to a new recreational lodge. The rules emphasized the importance of a lightweight bridge, and also restricted each builder — the 12-member MIT team had four — to a small area of the site. The restriction on movement made it more difficult to minimize builders’ downtime, a change that worked in MIT’s favor.
