2012 UAF Steel Bridge Team: Innovations in Design and Construction at Pacific Northwest Competition

The UAF Steel Bridge Team led by Amanda Green, Tripp Collier, and Jason Rein excelled at the 2012 Pacific Northwest Regional Competition. With a focus on reducing weight, increasing stiffness, and optimizing construction speed, they created innovative designs utilizing SAP for structural analysis. The team competed against 13 universities, showcasing their unique connection methods and construction techniques. Their dedication and teamwork paved the way to the national competition at Clemson, building on a legacy of success and overcoming past challenges in bridge engineering.

  2. DESIGN • MAIN REQUIREMENTS: • Each member has to fit inside a 6”x4”x36” box • Overall height, length and width of bridge • Construction rules and restrictions • WHAT WE FOCUSED ON: • Decrease weight • Increase stiffness • Quick construction speed

  3. BRIDGE Multiple designs drawn and tested in SAP (Structural Analysis Program)

  4. CONNECTIONS • 3 Types of Connections for Main Span • Dove tail • T-slot • Twist lock • Specialized cantilever connections We wanted to utilize a side rotation for each main span member for quick construction.

  5. FABRICATION • Steps: • Main-span members • rough cut • Mill • Top and bottom chord had plate welded • Connections • Welded entire main-span with connections in place • Cantilever

  10. 2012 PACIFIC NORTHWEST REGIONAL COMPETITION • April 27th-29th • Hosted By: • University of Washington & Seattle University • 13 Universities competing

  11. 2012 PACIFIC NORTHWEST REGIONAL COMPETITION DID AWESOME WE

  12. ONWARD BOUND TO NATIONALS WATCH OUT CLEMSON HERE WE COME!! • May 25th-26th • Hosted By: • Clemson University in South Carolina • 47 Universities competing

  13. Two National Titles – 1993, 1996 (tied) • 8 top 8 finishes at National Competition out of 12 attempts. • One provisional patent • Revolutionized method of testing students’ bridges at competition

  14. COULDN’T HAVE DONE IT WITHOUT HUGE SUPPORT FROM…

  15. History • 1993 – 1st time we competed; won all categories at Regional’s & all categories at National’s • 1995 – National’s: 4th place overall • 1996 - Disqualified at Regional’s; re-instated & tied for 1st at National’s. • 1997 - Did not send a bridge; bridge failed during testing. • 1998 – At Regional’s: Bridge collapsed during unloading; obtained a provisional patent for the concept. • 2001 – Bridge was not in top three at Regional’s. • 2002 - Bridge was not in top three at Regional’s. • 2003 - 6th at National’s • 2004 - 4th at National’s

  16. HISTORY (CONTINUED) • 2005 - Regional’s • Overall Performance (1st) • Economy (1st) • Efficiency (1st) • Stiffness (2nd) • Lightness (2nd) • Construction speed (3rd) • Aesthetics (10th) National’s - 6th overall • 2006 – No bridge • 2007 - Hosted Regional’s • 2008 - 8th at Nationals

  17. HISTORY (CONTINUED) • 2010 – Regional Competition. • Construction speed – (3) • Lightness - (1) • Display - (2) • Stiffness - (8) • Economy - (5) • Efficiency - (8) • Overall - (7)

  18. History (Continued) • 2011- Regional’s took 1st place in five of the six individual categories. They were: efficiency, stiffness, economy, lightness and construction speed.The team also won fourth place in aesthetics. The record at National’s was : first place in Lightness and placed 8th overall. • Construction speed (6th) • Lightness (14th) • Aesthetics (15th) • Stiffness (19th) • Economy (1st) • Efficiency (15th) • Overall (7th)
