Pretensioned Structures

Learn the essentials of design of pretensioned concrete structures. A common design application is in a wide range of building and dam structures where improved performance of prestressed concrete can allow for longer spans of material.

This module is currently offered in the Lyles School of Civil Engineering as part of the CE57200 “Prestressed Concrete Design” 3-Credits (CR) course in the area of structural engineering available to senior undergraduate/graduate students. It integrates science and engineering principles to design prestressed concrete members and structural systems. The application of scientific and engineering knowledge is demonstrated in solving engineering problems associated with the design of precast prestressed building members both composite and non-composite for superimposed loads, and one-way post-tensioned floor slabs systems bonded and unbonded also composite and non-composite for superimposed loads. Design of pretensioned Hollow-Core slabs, Double-Tee and I-Beam members, and one-way post-tensioned floor slabs is exercised using current building code requirements to provide experiences in realistic design practice. The following subjects are used to solve engineering problems: calculus and differential equations; use of computer tools, data manipulation, statistical analysis, numerical calculation, and reinforced concrete design principles.

The course is developed in three modules each of 1-CR. Module 2 (this module) is focused on the essentials of design of pretensioned concrete structures.

This course is available to practicing engineers for 1.5 CEUs for learners completing the course on the verified track.

Questions:

What is the difference between prestressed concrete and reinforced concrete?

Reinforcement can resist different types of load such as shear stress through the inclusion of reinforcement having higher tensile strength.

Prestressed concrete is when internal stress has been applied before the concrete is subject to load. This mechanism helps with structural understanding and design.

What is the difference between pretension construction and posttension construction?

Pretension is precast i.e. the steel is pulled before the concrete is poured. The elements are cast somewhere else and brought to the job site. The parking garage structure is made of multiple pieces and then brought together.

Posttensioned concrete means that the concrete is poured and then the tension is applied. Posttension requires the structure of the job site to be made.
