Fasteners for one of the entries in the National Student Steel Bridge Competition, held last weekend. As shown on page 38 of the 2010 rules, the staging area is 30 ft from the erection site and consists of four 7 ft by 10 ft areas designated for fasteners, members, tools, and temporary piers.

Forty-six teams competed in the 2010 National Student Steel Bridge Competition finals held May 28-29 on the campus of Purdue University in West Lafayette, Ind. The competition is co-sponsored by AISC and ASCE. Structured to simulate a real-world project, teams build a 1:10 scale model bridge to meet a particular challenge which is different each year. For 2010, teams constructed 21 ft 6 in. simple span deck bridges crossing a 13 ft 6 in. river and an adjacent 5 ft floodway.
A complete description is available in the 2010 Rules, which can be downloaded from www.nssbc.info (in the History and Results section).
The competition includes both designing the steel bridge and erecting it. Entries are evaluated in six individual performance categories: display, construction speed, construction economy, lightness, stiffness, and structural efficiency. An overall award is also given.
A list of this year’s winning student steel bridges is posted at www.aisc.org/steelbridge.
