PCI Online Academy:  Basic Prestressed Design - Session 3 Exam

This is the post-exam for Session 3: Code Requirements and Design Example – Part 1. This course explains the basic concepts and methods of prestressed concrete design. Attendees will work through the design of a simple prestressed concrete rectangular beam of a building. Both straight strand and harped-strand design will be covered in the example, exposing participants to realistic design conditions. The course is based on AC 318-14, ASCE-7 (2010), and IBC (2015).

After completing this session, participants should:

• Be familiar with the general organization of the ACI 318-19 code.
• Be able to select a preliminary size for a precast/prestressed beam.
• Be able to determine the preliminary number of strands needed based on allowable stresses at a section.
• Be able to compute prestressing force loss and adjust strands.
