2 MAIN REQUIREMENTS: Each member has to fit inside a 6x4x36 box Overall height, length and width of bridge Construction rules and restrictions WHAT WE FOCUSED ON: Decrease weight Increase stiffness Quick construction speed

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

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

16 Regionals Overall Performance (1 st ) Economy (1 st ) Efficiency (1 st ) Stiffness(2 nd ) Lightness (2 nd ) Construction speed(3 rd ) Aesthetics(10 th ) Nationals - 6 th overall 2006 – No bridge Hosted Regionals th at Nationals

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

18 2011- Regionals took 1 st 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 Nationals was : first place in Lightness and placed 8 th overall.
