The objective of this competition is to demonstrate the behavior of fiber reinforcement within concrete, to gain experience in forming and fabricating a fiber-reinforced concrete element, and to encourage creativity with compliance in engineering design and analysis.
Follow and comply with the Schedule, which can be found on the right-hand side; click on the button to download.
Meet the dates for team registration and submittals. Meet the times on the date at convention for the competition activities. Teams are encouraged to arrive at convention Saturday because the local time for competition on Sunday will vary.
There are two competitions for Prizes: Bowling Ball Design and Bowling Ball Analysis. Both competitions require knowledge and experience about concrete, fiber reinforcement, material behavior, and bowling.
Bowling Ball Design Competition
- Design makes choices with predictions.
- The design aspects of the competition occur prior to convention.
- Design is indeterminate and predicts how the bowling ball will behave.
- The predictions can be from calculations and practical knowledge.
- The design competition compares predictions and convention results, so each team is competing against itself.
- The winning team has the least difference between predictions and results.
- The intended analogy is about a project proposal (designed behavior prediction).
Bowling Ball Analysis Competition
- Analysis evaluates choices with testing.
- The analysis aspects of the competition occur during the convention.
- Analysis is determinate and tests how the bowling ball has behaved.
- The analysis will be from tests and practical experience.
- The analysis competition compares convention test results, so each team is competing against all the other teams.
- The winning team has more points than the other teams.
- The intended analogy is about an executed project (judged analysis testing).
A score will be awarded to each bowling ball for design and analysis. These scores will be converted into competition points based on relative importance and a 100-points based score. The team rankings will be based on the number of competition points earned as a result of each bowling ball competition. Both competitions have the same associated details. The six bowling ball tests and score percentages are listed and summarized as follows with the percentage of the total score for each competition:
- Specifications Test (10%)
Follow the directions for the schedule and the paperwork for the registration, submittal, and convention.
- Mass Test (10%)
Produce a consistent mass for each bowling ball.
- Diameter Test (10%)
Produce a consistent spherical shape for each bowling ball.
- Bowling Test (30%)
Score the highest in six-pin bowling rolled during the convention.
- Toughness Test (20%)
Provide the highest average load for multiple deformations.
- Load Test (20%)
Accurately predict the load at the maximum deformation.
Prizes will be awarded in both the Design and Analysis competitions. First, second, and third prizes will be awarded in each competition to the teams as defined in the rules. The awardees will each receive a certificate of recognition. Further recognition, if space allows, will be from ACI's website and Concrete International magazine. First-place prize money in each category is $750. Second-place prize money in each category is $500. Third- place prize money in each category is $250.
The Chair of ACI Committee S801, Student Activities, and the Chair of ACI Subcommittee 544-B, Education, will be the competition and presiding judges. These judges will appoint the other judges from these ACI Committees and other volunteers as needed.
The judges will determine whether or not the rules have been followed. The decision of the judges will be final, and appeals will not be considered. The judges retain the right to use any means or methods they feel are necessary to verify and enforce the rules and requirements of the competition. The judges retain the right to interpret, modify, or eliminate any section or sections of these rules as special circumstances arise. Judges may allow teams to compete that are ineligible for prizes.
ACI reserves the right to perform detailed examination and check entries for compliance with the competition rules. Examination will also be done after the competition. If examination shows that a team did not follow the rules, the team, their advisor, and teams from the same school will be disqualified. ACI Committee S801 will further document recommendations to sanction the team, their advisor, and/or school/university participation in future competitions.
