Pretensioned Structures

CE 59700

Credit Hours:

1

Instructor:

Julio Ramirez

Learning Objectives:

By the end of this course, you will be able to:

  1. Recall fabrication of pretensioned concrete members and in particular beam
  2. Recall the use of standard materials for prestressing application
  3. Recall and apply the principles of design for flexure, development length, and shear of pretensioned beams throughout the range of expected performance from initial to service and during unexpected overloads
  4. Recall and apply the guidelines and principles of design for flexure in fully bonded and partially bonded (debonded) beams
  5. Recall and apply the guidelines and principles of design for shear in pretensioned design of pretensioned structures for flexure and shear
  6. Recall and apply the guidelines and principles to estimate short and long term camber and deflections in precast prestressed concrete flexural member
  7. Recall and apply the guidelines and principles to estimate prestress losses in precast prestressed concrete flexural members
  8. Recall and apply the guidelines and principles to design composite precast prestressed concrete flexural member

Description:

In this 1-credit module, 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.
