Steel Bridge Competition - Scoring

Scoring

For a full description of the 2011 rules and regulations, including the scoring go to: Steel Bridge 2011 Rules

The different categories in the competition that will be judged are:

1. Display - Includes appearance of bridge, identification of the school on the bridge, and the poster that explains the thought process and includes sponsors, advisors, and technicians. (Display is only used as a tie breaker, however, the lack of information either on the poster or on the bridge itself will results in an added weight penalty to the bridge)
2. Construction Speed - The team that constructs the bridge with the quickest time (including added time penalties) wins this category
3. Construction economy - A formula is devised to calculate a dollar amount based on the number of builders, the time of the assembly, and the use of temporary piers. The team with the lowest dollar amount wins this category
4. Lightness - The team with the lightest bridge (including weight penalties) wins this category.
5. Stiffness - The team with the lowest aggregate deflection wins this category.
6. Structural efficiency - A formula is devised to calculate a dollar amount based on the weight and deflection of the bridge. The team with the lowest dollar amount wins this category

The overall winner has the lowest sum from the construction economy and structural efficiency categories.
