MST, UMKC, STL & SIUE ACI Student Chapters at 2019 ACI Fall Convention!

Congratulations to the teams sponsored by the Missouri Chapter of ACI for a great showing at the Student Competition during the Fall 2019 ACI Concrete Convention and Exposition in Cincinnati!  In the Type I Beam competition, Southern Illinois University Edwardsville brought home a 2nd place finish, while UMKC and STL had strong showings among the field of 38 teams.  Missouri Science & Technology (4th place) had a strong placement in the Type II Beam category. The Missouri Chapter of the American Concrete Institute is proud of how you have represented us well!

Fiber-Reinforced Polymer Beams
Student team's goals were:

  • Design, construct, and test a concrete structure reinforced with fiber-reinforced polymer (FRP) reinforcement to achieve the lowest cost-load ratio. Cost is defined as the calculated batch cost for concrete materials and chemical admixtures plus the cost of the FRP used to reinforce the structure; adjusted for forming costs for more complicated geometries and reduced by credits given for implementation of sustainable design concepts.
  • Predict the ultimate load.
  • Predict the load that will result in a piston deflection of 3.5 mm (0.14 in.).


A structure will be classified as a TYPE 1 structure if it is a straight prismatic beam; that is, its cross section is prismatic and the centroid of the cross section (based on the gross concrete cross section) does not vary along the span. A TYPE 1 structure may have a rectangular or non-rectangular, cross section; however, if the cross section is non-rectangular then a Complex Formwork cost adjustment will be applied as specified in Paragraph 4.3. Any structure that does not meet the requirements for TYPE 1 will be designated as a TYPE 2 structure.
