  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
