CE 57200 – Prestress Concrete Design

Credits and contact hours:

  • 3 credits
  • Lecture meets 3 times per week for 50 minutes per meeting for 15 weeks

Specific course information:

  • Catalog description: The course introduces students to the behavior and design of prestressed concrete structures and provides them the background needed to design various prestressed concrete members. Course topics include an overview of prestressing technology, loss of prestress, axially loaded prestressed members, flexural and shear behavior/design of prestressed members, and deflections. At the end of the course, students are expected to have the ability to describe the expected behavior of and perform basic design procedures for typical prestressed concrete members.
  • Prerequisites: CE 473 Reinforced Concrete Design
  • Course status: Required course

Specific Goals for the course:

  • Student learning outcomes - Upon successful completion of this course the student shall be able to:
    • Identify cases in which prestressed concrete is a cost-effective solution
    • Estimate prestresses losses
    • Design elements to resist flexure
    • Design elements to resist shear
    • Design composite beam elements
    • Apply code provisions to the design of structural members
  •  Relationship of course to program outcomes
    • Outcome 1: An ability to identify, formulate, and solve engineering problems by applying principles of engineering, science, and mathematics.
    • Outcome 5: An ability to function effectively on a team whose members together provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives.
