Matthew
Stuart, P.E., S.E., P.Eng.
Course Outline
This one-hour online course will enable you to obtain a general understanding of the most commonly used structural design philosophy and analysis of post-tensioned concrete in the industry today. This course will define the difference between pretensioned and post-tensioned concrete, and will establish the basis of design for post-tensioned concrete. A description of the methods of design including primary and secondary moment effects,load-balancing, preliminary sizing of members, tendon arrangement, losses and service and ultimate strength analysis will be provided. This course includes a multiple choice quiz at the end.
Learning Objective
At the conclusion
of this course, the student will:
- Be able to define the difference
between pretensioned and post-tensioned
- Be familiar with the basis of
design for post-tensioned concrete
- Be knowledgeable in:
primary
and secondary moment effects
load-balancing
preliminary sizing of members
tendon arrangement
Course Introduction
he structural
design of reinforced concrete can be divided into two categories;
- conventionally reinforced
- prestressed
Prestressed
concrete design can be further subdivided into pretensioned and post-tensioned
reinforcement. This subject of this course covers the design of post-tensioned
concrete only.
This course deals primarily with the design
philosophy and analysis of post-tensioned concrete. For detailed design
and computational aspects of post-tensioned concrete structures, the reader
should refer to PDHonline Course

Course Summary
The design of post-tensioned concrete uses the load-balancing method to represent the uplift provided by eccentrically placed stressed tendons. Typically the number of strands required is determined by service stress conditions rather than ultimate strength design. Placement of tendons and stressing sequences impacts both the design and construction of a post-tensioned concrete structure. Friction and wedge set losses have to be included in the calculation of the net post-tensioning force. Secondary effects resulting from the restraint of supporting members has to be accounted for in the ultimate strength design of any continuous section.Related Links
