Enhanced Bridge Design: From Prototype to Successful Final Structure

Team Bacardi's bridge project involved the design, testing, and final analysis of a prototype bridge. Initial flaws included uneven weight distribution and inadequate support at crucial joints. Through rigorous testing, adjustments were made, such as reinforcing the structure and ensuring even weight distribution. The final design, weighing 0.59 lbs, held an impressive 531.89 lbs, marking a substantial improvement of approximately 170%. This project highlights the importance of careful planning and design in engineering to achieve structural integrity and performance efficiency.

  1. Engineering 100:Bridge Project Group 6 (Team Bacardi) Jon Honari, Kevin Lam, Otis Chantharangsy, Ivee Ilao

  2. Design Ideas Prototype Bridge Process Testing/Results Prototype Analysis Flaws Improvements Final Bridge Design Testing/results Final Results Graph Analysis Failures Conclusion Presentation Outline

  3. Design • Arch Design • Proved to be strongest structure based on our research • Base • Flat and straight • Supports • Angle supports • Evenly distributed force

  4. Prototype Design

  5. Prototype Process • Arch • Supports • Road • Connections • Structural Reinforcements

  6. Prototype Process

  7. Prototype Testing/Results

  8. Prototype Analysis • Flaws • Uneven weight distribution • Not supported where bridge met jig • Ultimate reason for failure • Weak road • Sloppy design • Unnecessary weight

  9. Prototype Flaws Red: Excess Weight Green: Lack of Support

  10. Final Design • Excess weight was removed • Top section was more reinforced • Used wood glue instead of hot glue for the majority • Made sure weight was distributed evenly • Reinforced the legs where the bridge met the jig • Added more supports

  11. Final Bridge Prototype Prototype vs. Final Design

  12. Final Design (Completed)

  13. Final Testing/Results

  14. Final Design Failure Important joints were overlooked and were not supported correctly

  15. Final Analysis • Overall, very good improvement • Bridge weighed 0.59 lbs • Bridge held 531.89 lbs • Performance = Successful • With more supports in the correct places we believe the bridge could hold much more weight

  16. We conclude… • Spending more time on the construction yielded better results • About 170% improvement • High efficiency ratio • Endures a high amount of pressure • Lasts under consistent amount of low pressure • First Bridge: .56 pounds, held 296.00 lb • Final Bridge: .59 pounds, held 531.89 lb
